Hi @PopPop123
Some of the things you have mentioned here are experiences I have also had with my DFiance. The staying out all night drinking, being a complete prick and putting our relationship under so much strain and pressure that I thought I couldn't take any more.
He used to go out drinking, tell me he would be coming home and never appear. Even when I would text him to make sure he was ok, he would lie and fob me off saying he'd be home in an hour - that old chestnut. This happened on more than one occasion and it resulted in making me feel very uneasy when he did go out, so much so that it would make me feel physically sick and incredibly anxious. This was when we both had our own houses, so he'd end up back at his instead of mine like we had agreed before he went out.
People would call me a mug for staying with him, I made excuses too and looking back I probably would have left him earlier on in the relationship if we were to do it all over again.
However, I had my reasons for staying with him. I got pregnant, through carelessness and generally being shit at taking my pill, also suffering from mental health/depression at the time. So that swayed me - the baby.
Then our son died, he was stillborn at 38 weeks. This pushed us closer together and I was at a stage where I desperately needed DF and he did me because of the devastation and heartbreak we went through together.
However losing a child was not enough to make him stop being a selfish prick and it got so bad that I told him I couldn't take anymore and I wanted him to leave.
I then found out that I week that I was pregnant again.
We agreed to try to work on "us" for the sake of the child. Following our loss we both wanted to have another baby and although the timing was poor we took it as a blessing.
I told DF that he MUST change his behaviour if it was to work. I told him he had to make the effort to change and since then he has been going to weekly therapy sessions and things have been much better.
He is not drinking anymore, not going out like he used to and we have been much better as a couple.
I do sometimes worry that he will go back to how he was before. He assured me he doesn't want that and he is doing his best to make positive changes to make our lives better and the relationship stronger.
We have been through a lot of shit together. He has made mistakes and so have I.
I don't think the anxiety will ever fully go away for me. However I'm doing my best to deal with my issues as he is his. If he had refused therapy I think it would have been the end for us, I really do.
I sometimes feel like a total mug for letting him get away with so much but I know that he is a good person, he could just never properly control himself when it came to alcohol. He's learning now there's more to life than that, which is great.
I think if you want your relationship to work you need to have a sit down proper conversation with your DP. Try to get him to understand how you really feel. If he won't make changes then you have to ask yourself if you are happy to continue living the way you are. I can pretty much guarantee that your anxiety won't go away until he does something to make you believe he is changing and wants to stay changed. I still worry but I'm starting to feel better and more positive.
I do feel that relationships should be worked at, I don't like to just give up, however there are of course limits - you have to work out what yours are.
