Colleague and former lover has become obsessed with me

Just over ten years ago i left a physically, emotionally and financially abusive marriage where I was a SAHM, got a job, full custody of kids and now have a successful career. ExH is in jail.

When I first started working over a decade ago in the same company I am in now, I rebounded into a very stressful (and I would say again, abusive but in a different way) sexual situation-ship with a more senior person at work from another department. Will call him B. To cut a long story short, I believe B saw my vulnerability at the time and we started sleeping together after work some days. B was single, but I would discover after a year, he was completely obsessed with another colleague of ours who he had, had a relationship with previously and who had broken things off with him.

in the early stages of us sleeping together I was looking for emotional refuge, ignored the blatant red flags and developed feelings for him. B filled most of the time we were together and not having sex confiding in me about his heartbreak over our other colleague. I am afraid my self esteem was so low at the time i was a willing listener to his heartbreak. I was also worried about financial security at the time and affording to bring up my DC so figured I might as well stay on good terms with him and spend the time as his therapist when he asked.

He made out he and this other colleague were in a grand love story, she was “the one,” she’d “faded away” because of issues in her own life and he was devastated and would never get over it. He used to tell me how he would spend hours staring at his phone willing her to call or text, make trips to hotels near her house and stay there in the hope he might see her. He showed me streams of WhatsApp’s he’d texted her through the night vascillating from angry to sad to begging. He was always vague about the reason for their breakup but said it was due to tragedies in her life that made it impossible for her to see him. That circumstances had torn them apart. At the time, all I could feel was very confused. He and I were sleeping together and I had feelings for him but he was just endlessly heartbroken and obsessed with our other colleague who was very obviously unavailable.

Meanwhile in the background he used me 24/7 like a crutch and emotional confidante. She had texted, she hadn’t texted, he caught sight of her in the office. He would suggest he and I go to lunch and work meetings to where he saw in her diary she might be, and that he would “offer me advice” and give me experience etc where he would use the entire time to talk about her. Naturally because this enabled me to socialise across the business more thanks to him, I met more people, got more opportunities and advanced.

fast forward, seven years later, a decade working at the company, we have morphed into more of a relationship over the last three years and now have this decade of shared sexual, emotional and professional history together . He is now approaching retirement and I am above the level he was when I came in. The other colleague he was obsessed with has left, and guess what? He has now become obsessed with ME.

i can’t remember when exactly it flipped but it was about two years ago when my DC had become a bit older, I had more freedom and I decided to date again. As we were not committed to each other and we had the history of his obsession with our other colleague, I assumed he’d be fine with it. He was not at all, and has gradually become stifling and suffocating to the point I feel physically ill when I am around him.

he has completely denied our history and maintains we were in a relationship for ten years. He is doing all the things I watched him doing with our other colleague - monitoring his phone, checking up on where I am, appearing near my house, standing and staring from across the office to the point that other people think it’s very strange. He has emotional outbursts over professional emails where he reads into my tone and thinks I am ignoring him or giving him a message. Some days he leaves me over 50 missed calls.

I have pointed out to him that he is repeating a pattern I have seen first hand with our other colleague. I have told him he has fallen into limerance, suggested he get counselling. I have been angry, understanding, compassionate, direct, all while telling him we were and are not in a relationship but he just rewrites history and gets very angry at the idea “that I would ever compare our love story to the superficiality of his and ex colleague’s relationship”

it’s hard to just cut him off because we work together and because of this shared history our professional lives are quite intertwined. He has also helped me a lot professionally as someone more senior and I am grateful for that.
I suppose I am writing this just to vent. Can you offer any insight into what is going on here and how I can make this go away?

Jesus! He is harassing you.

Purpleandredandyellow · 23/04/2025 11:26

If you want it to stop, you need to explain to him you will be putting in a harassment complaint against him with the police unless he stops the harassment immediately. It doesn’t matter that you hve a shared history or have benefited professionally from your relationship. Hopefully that threat will stop the phone calls and stalking.

It is very psychologically damaging for you and you never know if he could turn violent - it does happen. It may get worse when he retires when he has more time on his hands!

alcoholnightmare · 23/04/2025 11:35

Sorry if I’ve missed this, but are you still casually seeing him or not?

canthavethatonethen · 23/04/2025 11:53

He thinks he can get away with it because he's more senior to you, and therefore has authority to influence your career progression. In other words, he expects you to play his game or he could make things very difficult for you professionally.

BobbyBiscuits · 23/04/2025 11:59

Tell him you are not interested in any further correspondence with him. If he continues you will contact the police. Then block him.

Changeissmall · 23/04/2025 12:03

Not really clear if and when your relationship with him ended but yes. Tell him you will involve HR and then do it.

PeggyMitchellsCameo · 23/04/2025 12:13

He was mentally unstable when you met him.
He is mentally unstable now.
Just because he has ‘helped’ you at work does not give him the right to harass you in real life.
Sadly, you have had some sort of connection for a decade which you have allowed to continue. You knew what he was like, and for whatever reasons have stayed around him.
You could speak to him directly and be very clear about your stance now, but I’m afraid if you communicate with him anyway beyond that, it will feed this obsession.
He clearly needs professional help, which you have suggested.
You could approach HR.
You could find another job.
But ultimately this man is going to continue with any form of what he sees as connection.
The only real solution is removing him from your life on every level.

juststrutting · 23/04/2025 12:26

No, no, no, no. Go to HR. Get it to stop. He cannot behave like this. It is harassment!

canthavethatonethen · 23/04/2025 12:39

Is this harassment just during work hours, or does he do it outside work as well?

Bloodorangey · 23/04/2025 12:51

Thank you very much for all replies. And for making me not feel crazy. He is literally gas lighting me to agree that I am trying to break up a ten year committed relationship of soul mates. We last had sex about 2 years ago before he flipped.

i Take you all seriously when you say it’s harassment and I need to contact HR / or police if necessary.

what is so weird and ironic in this case is that I have seen this play out with a whole other person. Almost word for word and the same actions and beliefs from him. Because I have known him a decade, I know him well, I know how insecure he is and how the feelings he has for me aren’t actually real. He is projecting on to me the solution to fill an emptiness he has inside. I have told him this and he just gets really upset and angry. Whenever I am near him I feel a huge emptiness and neediness in his energy which is extremely uncomfortable. It’s like I have suddenly become the solution to all his problems. I don’t know how he thinks he can behave exactly the same way with me as he did with the previous colleague and make out that this time it’s “unique?!”

Genuine question…. Do you feel guilty now for not supporting/backing up your previous colleague?

It’s in and out of work 😱

she and I never had an interaction. Our paths didn't cross professionally and he had sold me a story from the beginning of all these tragedies that has happened in her life and how she was a broken person. She was also gearing up for retirement at the time and very senior, so above my pay grade.

I have had a thought about contacting her though. I don’t even know how I’d start the conversation.

Bloodorangey · 23/04/2025 13:05

When I look back and he was using me as an accomplice in “stalking” her, he always used to make it look like he was caring for her by following her around and checking in on her. He also used to tell me he would see her regularly outside of work because they had a forbidden love. I was completely brainwashed by it at the time but now I see it more clearly.

NamechangeJunebaby · 23/04/2025 13:08

@Bloodorangey are you in a firm where you had to report relationships with colleagues and if so did you do that? I was in a similar position to your first colleague and when I left he would turn up at my new workplace or hover at my bus stop. I had to block him everywhere and I did threaten to report it to HR. He then had an accident which meant several months off work, and thankfully has lessened contact. Though he still contacted me at my new work and I had to reveal it to my new employers (I gave them full access to my WhatsApp). They were concerned, noted it as harassment and I left it in their hands to consider reporting him to the professional body who governs us (SRA - legal profession). Not really sure what has happened but it’s very quiet on the messaging front now and I hear from him maybe twice or thrice a year with a basic “are you okay” to which he gets a basic affirmative response.

Definitely speak to someone in HR, in a confidential setting, and explain the issues you’re having as he doesn’t appear to be mentally stable and you need to protect your position as he has the potential to blow up your life. This is harassment. I would hazard a guess that the first colleague was only the first you’re aware of and he has done the same to others before her too.

I hope you’re okay. Never allow yourself to be alone with him - make sure there is always a witness.

It sounds as though you both used each other to be fair, but obviously for very different reasons.

I think the only answer now is to keep it to 'strictly work contact only' and keep to it 100%.

There seems to be no inbetween with this guy, so it's pointless looking for it.

I’ve been worried about this - that I “brought it on myself” which is why I posted here to get some second and third views.

OoooopsUpsideYourHead · 23/04/2025 13:28

Brought what on yourself?

I'm just pointing out that for a long time, you both got something out of it that you needed, no matter how strange it was at the time.

Now you're getting nothing out of it, it's time to tell him in no uncertain terms that it's work talk only.

You have every right to do that.

CanOfMangoTango · 23/04/2025 13:29

How close is he to retirement?

I'm wondering if it's short enough that you could wait until he's left your work & then speak to police about the harassment.

It's not right but I would be worried about him trying to sabotage you at work if you raise it now.

But pp are right, his behaviour is inappropriate and needs to stop.

IstayhomeonFridaynight · 23/04/2025 13:57

Have you told him very clearly that he's crossed over into harassment and that you don't want any contact from him anymore? If he gets upset or angry you need to walk away/hang up or block him. It's not something that is up for debate.

You need to talk to HR to tell them you had a relationship with him, it's over and he is harassing you. They will need to talk to him, and ensure you're not working together. I don't think you should mention his previous relationship/obession with a colleague, it just muddies the waters.

If he continues after that, I think you have evidence to go to the police.

You didn't bring this on yourself, you had a long drawn out 'situationship' with him, it's over, he needs to back off.

That he did this before is not your responsibility.

kellygoeswest · 23/04/2025 14:05

I would send him a final text message or email clearly communicating the boundaries you require going forward, e.g. that you want a professional relationship only - and request that he respects this.

Obviously from what you've said, he won't respect this, but from now on keep a diary/log of every instance where he acts inappropriate. Whether its repeated text messages/calls, emails at work, or showing up. Log everything.

Report him to HR and, if you deem it necessary, the police... it doesn't matter about your past with him, this is considered harassment/stalking.

Spareducedpriceoffer · 23/04/2025 14:30

50 calls per day

Is that to your work phone or to your personal phone ?

If it is your personal phone, change your number

Ceramiq · 23/04/2025 14:34

Obviously there is a complicated back story but that doesn't make you guilty of anything at all if you want this "situationship" to be over and to embark on looking for another, more mature and fulfilling, relationship. You don't owe this man anything, despite his opinion to the contrary.

Endofyear · 23/04/2025 14:48

I think you need to put in a complaint to HR about his harassment and also the police if he's stalking you outside of work. Block him on your phone and email so that he isn't able to bombard you with messages.

I know you were vulnerable when you first met him but given your description of his behaviour towards his previous girlfriend, did it not worry you that he was harassing and stalking that poor woman? Did you not see that he had severe problems? You've been in a relationship of sorts with him for 10 years, that is a long time and I'm surprised that it's taken you this long to see him as he is.

The man is a fucking nutter has mental health issues, and you are giving his actions and intentions way too much headspace. What he says and why he is doing it is irrelevant.

The only thing that matters here is his harassment of you, both in and outside work, and he has to be made to stop one way or another.
