How to deal with work colleague?

91 replies

Shs726 · 12/10/2025 22:31

I am in my early 30s and married. He is in his 50s and is married (on paper but live together).

I’ve worked with him for five years, and there’s never been an issue.

A few months ago, while working on a project, we started talking about our upbringings. He asked about my dad, and I mentioned that he wasn’t around and that we don’t have a good relationship.
Later, he messaged me saying he felt really sad for me and was surprised by what I shared, but he was glad I opened up. I was a bit taken aback, as I didn’t think I’d shared anything too personal, but I didn’t think much more of it.

He then sent a message asking if I’d like to meet for lunch on our day off. I politely declined, explaining that I don’t hang out with the opposite gender one to one as it’s a boundary my husband and I have. He respected that.

A few weeks later, he messaged me again, saying he’d visited a chocolate factory and bought chocolates for me, which he’d left at the locker. I thanked him but said he didn’t need to do that. I didn’t collect them, but he later messaged again, reminding me to pick them up.

At the time, I didn’t think much of it other than wondering why he’d done that. My colleagues occasionally get each other small treats, usually as a thank-you for helping with something. I thought it was a one-off, and since I’ve received chocolates from other colleagues before, I didn’t think it was anything more than a kind gesture.

However, later on, he got me a cookie and cake. Again, I just thought he was being kind and accepted it but said no more treats after this. Then a week later, he messaged saying he’d bought me drinks and more chocolate. I replied that I couldn’t accept them, but he insisted I do so, saying he was just trying to be nice. I left it for a few days, but then he messaged again, saying he had no use for them and asking me to please take them. I agreed but asked him please not to buy me anything else.

A few days later, after a busy day at work where I had to work through lunch and stay late, he came to my desk the next morning (which I was sharing with another colleague). He placed coffee, cookies, and lunch on my desk, saying, “Here’s the stuff you asked for.”
My colleague gave me a strange look, and I assumed it was because, one, I never ask my colleagues to buy me anything, and two, everyone knows I’m particular about my coffee and don’t drink that brand.

I was taken aback by why he did that and by his false claim that I had “asked” for it. I didn’t want to embarrass him, so I simply replied, “I’ll sort you out with the money later.”

When I later saw him, I took out some money to give to him for the items. He refused, insisting that it was a gift and that he’d noticed I might not have eaten earlier because I was so busy. He just wanted to show he cared. I thanked him for the gesture but told him not to worry about me and to stop buying me things. He gave me a spiel about knowing I’m independent but that he was just trying to help.

A week later, he said he’d left more treats for me. I replied saying I wouldn’t accept them. He insisted I take them, saying it would be the last time. I told him that if he bought me anything more, it would lead to an argument. He agreed, but added that he couldn’t wait for our first argument. I didn’t say anything else.

Now, things at work are changing. He continues to make me instant drinks and places them on my desk. The problem is, I don’t drink instant coffee, and everyone at work knows this. Also, I never ask anyone to make me a drink. Additionally, whenever I’m on calls, he comes over and starts doing my paperwork. I find this annoying because I’ve been managing on my own for five years. When I get off the phone, I thank him but tell him I’ll handle it myself.

Then, one day, he gave me an envelope. I thought it was work-related, but when I opened it at home, I found a mixtape he’d made for me; despite knowing that I don’t listen to music, whereas he’s a big music fan.

One day, I had a headache, and I was feeling a bit down. He asked what was wrong, and when I told him, he suggested I take some medicine. I declined, saying I’d manage. A few hours later, he went out and bought me three types of medicine.

I told him I wasn’t going to accept it, as it made me and my husband uncomfortable with the amount of stuff he was buying me. I explained, as politely as possible, that I appreciated his thoughtfulness but that he needed to respect my boundaries. I told him this privately.

At first, he said he understood and that it was no problem. I thanked him for his understanding.
When I got home, I received a long message from him. He said that I had embarrassed him and made him feel awkward. He claimed that he and others always compliment me at work, but I brush it off as if it means nothing, which had damaged his confidence. He also said that I make him feel insecure, and that I’m too stubborn to accept anything. He emphasised that he was just trying to help and that he always feels like he has to walk on eggshells around me, but he was finally going to be honest.

The message went on and on. I simply replied, apologising if I’d made him feel that way, but reminded him that he continued to buy me things even after I asked him to stop. He then apologised again, repeatedly. I accepted and told him not to keep apologising, that it was fine and over. Later, he sent me another message about how he spent his day off. I didn’t reply. Then he sent messages about someone we both know. I replied, keeping it short and sweet.Then he apologised again, and told me about his son’s birthday. I wished his son a happy birthday. He sent some more random texts which I didn’t respond to.

Finally, he sent me a message that was around 4000 words long. It detailed random bits about his childhood, his work, his folks, and how sorry he was. He said he knew I love my husband and respect that we have different beliefs, but he cares so much about me. He wrote that I inspire him and that I’ve lit something inside him that was dormant. He said I make him feel human, and that when I respond to things he tells me about himself, I’m never judgmental and am always empathetic. (Bear in mind, I’ve never asked for him to tell me his business). He acknowledged that he shouldn’t message me so much, but that he couldn’t help it.

I didn’t respond, but I’m in shock. What is this behavior?

Bloody hell OP, how have you tolerated this for so long. You must have the patience of a saint. I'd have blown by now.

‘This is inappropriate. Do not message me again or I will go to HR’.

i have reported to HR
no threats, just do it

BunnyRuddington · 13/10/2025 07:42

Are HR available to you @Shs726? I work for a big organisation but HR aren’t in site and we have no access to them.

I would have to go through my Manager. If it’s similar for you, I would make sure your Manager knows that the next step is the Police.

User2025meow · 13/10/2025 07:54

100% stalking behavior, police reportable already as others have said. He is pushing boundary after boundary with you, each little one he succeeds in violating gives him the impetus for the next one. Report to HR and be prepared now to shut him down 100%. Do not worry about his feelings. You are way too nice as a person and this will make you a target in life, I’m sorry to say. You’ll really have to work on your boundaries at some point. Take this extremely seriously, I suspect he will escalate. He’s not to interact with you anymore unless it is work related and HR should explain this to him, better yet it should be taken care of so he has no reason to interact with you at all and really should leave the company. Where you see it is most disturbing is where he starts to blame you for your reaction to his harassment! . He claimed that he and others always compliment me at work, but I brush it off as if it means nothing, which had damaged his confidence. He also said that I make him feel insecure, and that I’m too stubborn to accept anything. He emphasised that he was just trying to help and that he always feels like he has to walk on eggshells around me, but he was finally going to be honest.

You are way too nice as a person and this will make you a target in life, I’m sorry to say.

Bollocks. I'm nice and friendly but not a doormat. You don't have to be horrible to people to be assertive.

Definitely report to HR and let them know that none of it was remotely initiated by you.

Cucy · 13/10/2025 08:08

Firstly, stop texting him.
Even if he’s texting about work, do not reply.

Secondly, ask for a meeting.
Tell him that the amount of attention he is giving you is making you feel uncomfortable and if he carries on then you will be forced to find another job.
Tell him to not buy you anything else or make you drinks when you haven’t asked for them.

TimeForATerf · 13/10/2025 08:14

This really should have been nipped in the bud, I feel for you OP, it’s the same old story, he knows you have a vulnerability which he has zoomed into, he probably knows you won’t complain or be able to tell him to just fuck off. You definitely need to go into the office and complain to management, tell them everything you’ve told us, maybe write it down in a timeline and keep that timeline and update it if anything else happens.

Please do it today x

oh, and block him ASAP

Rizzla · 13/10/2025 08:18

Block number, tell HR immediately.

you needn’t entertain anything he says, apologise, or respond to anything, this is really concerning behaviour

GnomeDePlume · 13/10/2025 08:20

Do NOT have any sort of private meeting with him. He has become obsessed with you and will interpret any interaction with you as evidence that you are interested.

Time for your manager/HR to be involved. No warning that you are going to do this. It is way past that point.

BunnyRuddington · 13/10/2025 08:21

Please don’t do this OP. It’s up to his Manager to tell him to back off or it’s all reported to the Police and why should you leave?

SparklyGlitterballs · 13/10/2025 08:24

The polite shutting down of the situation hasn't worked and this has been allowed to go on for far too long now.

Immediate step - block him on your phone. Stay in the team WhatsApp if you want but block him from messaging privately. Don't respond to him or warn him.

Second step - speak to HR today, or your Manager if you have no access to HR. He's not listening to you OP and he's obsessed. You need to shut this down once and for all.

If he brings anything to your desk today in the meantime then forget about being nice to save his feelings, shut it down "John, I've asked you repeatedly to not bring me things, please take this away, thank you" then straight back to work. If he comes over to "do your paperwork" when you're on a call then a firm hand on top of the paperwork and indicate no. Stop allowing him to do these things. It sounds as though you need to be far more assertive in these situations.

Suednymph · 13/10/2025 08:34

He is unhinged. Block his number and report him to whomever you need to report him to. He is grooming and manipulating you especially when he alluded to you asking him for things. You should have then replied you did not ask for anything, he was doing this so other people would think you had as he knows his actions are wrong but he is trying to make out you have something going on between you. If he brings you another drink pick it up and drain it down the sink. Respond with 'I said no' every single time he brings you anything or tries to talk to you until HR have spoken to him.

FutureMarchionessOfVidal · 13/10/2025 08:40

Oh god please go to HR immediately. Also go to the police. Ask to speak to an officer who is trained in dealing with stalking type behaviour & ask for advice about what you should be doing at this stage.

UnimatrixZeroOne · 13/10/2025 09:20

This is stalking. Stalkers have killed their victims. Go to the police.

socks1107 · 13/10/2025 09:26

You need to escalate this to a manager or HR. This guy won’t take no and is now manipulating you and guilt tripping you.
I wouldn’t respond to another thing and see someone today about his inappropriate behaviour

2chocolateoranges · 13/10/2025 09:31

Make a complaint to your manager and escalate it to HR if it helps. Stop being polite to him, be assertive and tell him this all stops as it’s harassment.

don’t engage in any conversation.

GnomeDePlume · 13/10/2025 10:25

Be prepared for him to turn nasty if he is thwarted. I'm not saying he will but be on your guard. He probably sees his behaviour as fine, lovely even.

Be prepared for him to try and talk to you. Is there anyone you can leave work with?

If you drive to work, check your car before getting in. Be prepared to report any new damage.

Be prepared for 'number withheld' phone calls.

Any/all of the above are escalations. Hopefully they won't happen but forewarned is forearmed.

Any escalation needs to be a police matter.

LifeInAHamsterWheel · 13/10/2025 10:31

This is stalking and harassment. You've asked him repeatedly to stop. You now need to hold firm. Message him to say that you're very uncomfortable with the level of contact, that he is not to contact you again and that you're blocking his number on your phone. Tell him you're only going to engage with him on work matters from now on. And then you must stick to that. Don't get dragged into discussions about it etc. and don't feel any guilt. I'd also tell HR or your manager but at the very least cut all contact and block him.

DramaQueenlady · 13/10/2025 10:33

That's classed as serial harassment and a sackable offence. You poor soul. Regardless of your beliefs most people would feel as you do. Report him.

Tillow4ever · 13/10/2025 11:09

This is not your fault. You have been polite and patient but this man is taking advantage of your good nature. I agree with others that you have become an obsession for him. It’s definitely stalking/harassment and you can’t just keep telling him no as he’s ignoring you. Definitely report at work (and don’t feel guilty - you told him multiple times that you didn’t want these gifts, etc) and I’d consider a police report as well. He may become dangerous, so tell people around you what he’s been doing so they know to look out for your safety!

Good luck.

TreadSoftlyOnMyDreams · 13/10/2025 11:14

I would feel really unsafe. Report him and urgently.

Needtosoundoffandbreathe · 13/10/2025 11:20

Urgh. He sounds like a stalker. "Stop contacting me, this is inappropriate", is perfect then go to HR and your manager. He will undoubtedly say you are friends or, worse, you've been leading him on, despite the number of times you've said no to him. Block him.

pictoosh · 13/10/2025 11:31

Ohh I wouldn't like this at all. He's crashing through your boundaries even though you have been clear his 'care' is unwanted as is his attention. He's persistent and that would ick me right the fuck out.

I know it's an awful prospect but you should escalate this above to HR or whoever your company/organisation has in place to deal with staff issues.
He has become fixated on you and that's completely unacceptable.

TheSpiceoflife2day · 13/10/2025 11:54

You have been too nice for too long !

Tell him to stop or you will report him

Give all gifts back

Block

Actually this is really good advice. No matter what your Manager and HR have said i would call the Police and ask to speak to to the officer who deals with stalking.

I unfortunately was the target of a stalker a long time ago and stalkers often dont behave in a way you’d expect.
