To start resenting my BIL

31 replies

AnaisVB · 23/11/2025 17:45

My sister is married to a really lovely man. They have a three year old DD.

My BIL is a great partner and he adores my sister. He’s great with my kids, is close to all our massive family and has lovely friends, he works hard etc

BUT there is something driving a wedge between them and I can see it hurting my sister.

Basically whenever he goes out - which is fairly regularity due to his job- he tends to get really drunk and come home late and does stupid things . The latest is he got up in the night so drunk he thought the bedroom was the bathroom - you can see where this is going! Then he was too hungover the next morning to drive them a couple of hours to see some family . Or he comes home and even if it isn’t late he carries on having a drink and then is disruptive , playing guitar or not coming to bed until late . My sister works full time in a busy job and is fairly regularly missing sleep because of it . She also has had some health problems lately and is more tired than usual and I feel like he should be taking this more into account.

When he is sober and in the cold light of day he is always apologetic. They’ve even talked to a therapist about it (and the therapist has agreed with my sister that it feels unfair to her)

The other day my sister looked broken, she is feeling fed up and feels let down because he doesn’t seem able to change even though he says he will.

She doesn’t want to be a killjoy and is really relaxed about him seeing friends etc but now it feels like when he goes out she gets anxious because she is worried how the night will go.

Fyi They don’t have a spare room and when he comes in it’s quite disruptive as it’s only a two bed apartment.

Sidenote our mother was an alcoholic growing up and we might be really hypersensitive to alcohol related things, so it’s potentially triggering her, and she doesn’t know if she is being unreasonable.
Has anyone had similar or been able to address it?
It’s not my place to say anything but I’m worried about her and a bit him too, but I’m starting to feel annoyed with him because he’s making her unhappy and she’s not feeling heard . Does it sound like he has a problem or is it just normal?

Sorry for long message! x

He has an alcohol problem.

Unfortunately there is nothing you can do about it other than support your sister.
And encourage her to seek advice from Al -anon or similar organisations that offer help to families of alcoholics.
If he at the stage where he can't differentiate between his bedroom and the toilet he has a serious problem.

TomatoSandwiches · 23/11/2025 17:57

I presume they have no children?
If so I would be advising her to leave ASAP, he is an alcoholic and he will continue to be disruptive until he has hit rock bottom. He isn't a partner, he is selfish and cruel to let your sister down so much when she is struggling and they've already talked about this.

toomuchfaff · 23/11/2025 18:04

If there is no spare room, and he is apologetic and aware of his problem, maybe the suggestion is that if he is going out with friends then he doesnt come home. So your sister isnt disturbed.

You know where this is going...

DisforDarkChocolate · 23/11/2025 18:07

He's not lovely. He's an abusive drunk.

She needs to leave him before it gets worse.

BoyMumFTM345 · 23/11/2025 18:10

He's an alcoholic. I know a few. They never changed.

Your sister has to leave him. Or she'll be a bitter old woman one day who will have wasted her while life on an alcoholic.

FuzzyWolf · 23/11/2025 18:12

I’m struggling with you saying he’s a lovely man and great partner before then going on to describe a selfish alcoholic.

Andromed1 · 23/11/2025 18:14

He's an alcoholic OP and however lovely his basic personality is, he'll keep on doing stupid and even dangerous things until he gets it under control.

333FionaG · 23/11/2025 18:41

As a recovering alcoholic, I can say with confidence that BIL has a drink problem and unless he addresses it, his life will go downhill quickly.

I know what you mean but he really is a lovely human which is why it’s so hard .

But it does feel selfish and I think he needs help. It’s useful to hear your take on it.

Thank you for the insight. Would you say it’s alcoholic behaviour if he doesn’t drink all the time? He just drinks too much when he does drink?

I’d assume he just hasn’t grown up and realised he’s now married with a child. your sister needs to have a proper talk with him

Thank you. I need to hear it so I can help her see it. We get muddled because of our Mum and tbh I know quite a few men than regularly get wasted and people just think it’s funny!
I really need to hear the truth though thank you.

They have a three year old DD . I know it’s such a let down.
it’s really good to hear outsiders perspective because I know so many people that think getting drunk is normal.

Getting drunk occasionally happens.

Frequently and resulting in domestic squalor, disturbance and disruption of family life is a problem. It’s humiliating to be late or absent due to his drinking, and it is no way for the 3 year old to grow up.

As you and your DSis know.

In her shoes I might stop being patient, enduring and understanding…they’ve got the counselling T Shirt… and absolutely blow up at him. Tell him how he is ruining her life and will ruin their child’s life and she will leave if he doesn’t get help and sort himself out immediately,

And then leave if he does it again.

Either his fear of losing his wife and daughter will shock him into action or it won’t.

But continued beseeching will just establish the pattern where he causes upset…apologises…on repeat.

Cherrysoup · 23/11/2025 19:37

Absolute arsehole, not remotely a lovely guy. He’s repeating horrible behaviour and disrespecting her and the 3 year old by disrupting their sleep. I’d be gone.

Poppyseeds79 · 23/11/2025 19:51

AnaisVB · 23/11/2025 19:00

Thank you for the insight. Would you say it’s alcoholic behaviour if he doesn’t drink all the time? He just drinks too much when he does drink?

Whether or not he's an alcoholic doesn't really come into it. What he definitely is doing is binge drinking whenever the opportunity pops up, and then acting like he's still young, free and single.

Playing his guitar when his 3yr old and DW are trying to sleep is an utter piss take. He's not stupid as he apologies show once he's pulled up the next day. But it's not supposed to be your Dsis job to have to mummy him around this.

If he's too much of a plank to realise that him "letting his hair down", every opportunity he gets is just not on when he has responsibilities. Then your sis should maybe start talking divorce.

IndigoIsMyFavouriteColour · 23/11/2025 19:58

Oh your poor sister, that must be awfully difficult for her. I agree he needs help to see what he is doing to the family unit by behaving in this way but if he’s lovely most of the time it makes it harder.

He needs some sort of shock to make him realise what he is doing but I don’t have any suggestions as to what that should be. He needs to stop behaving like he’s single, basically.

Thank you. It really is heartbreaking for me to watch, they have such a lovely life until he drinks. Alcohol played a massive part in our childhood and I’m so sad for her to be going through this now, especially as I honestly can say without drink he’s one of the best people I know. He needs help and all these messages are really helping me see it clearly. I can’t do much but at least I am confident that it is a problem and help her to
address it when she wants to.

He has definitely got a problem with alcohol. You don't have to be drinking every day to be like that. His behaviour is causing issues with his wife so that should be enough to stop. But he can't. So he has a problem.

My ex boyfriend would be like this. He also peed in our closet when drunk. I found him sleeping spread eagled on the lawn another time. He just wanted to relive his fecking teen years or something I'm sure.

It really caused us issues - he would make me feel like shit that I was upset he got like that and Im thankfully far away from that madness.

This WILL affect the daughter. All you can do is support your sister and wait for her to realise.

Mehmeh22 · 23/11/2025 20:15

Oh and everyone said how nice my ex was. Which made it even harder cause I thought I was losing my mind.

hl8 · 23/11/2025 20:24

You say he adores your sister but if that was the case he would be respectful to her feelings about his behaviour and especially respectful to her not being well recently. He is displaying selfish behaviour and I think your sister deserves more than what she is getting.

PigeonsandSquirrels · 23/11/2025 20:24

It seems to be really common behaviour if Mumsnet is anything to go by. Unfortunately some of us can’t have alcohol because it turns us into inconsiderate dickheads. It’s why I’m now teetotal. My husband tried to talk to me about it over and over and over again. It was only when I caused something major that I came to the realisation that I had to stop. To me, he sounds pretty identical to how I was and I was a problem.

Hankunamatata · 23/11/2025 20:31

Dh was a bit like this but pre kids.
After the second incident it was agreed if he went out drinking he stayed at a mates or his mums.
Funnily enough he wised up.

Also alcoholic is a less useful term as people can deny it when they don’t drink every day.

Alcohol Use Disorder is more commonly used now.
