Is my bf abusing/controlling?

I think I'm asking this qeustion because I'm in denial but I'll just tell you what happened.

For the past two months he's been super argumentative about everything. Nothing I do seems to be right even though I try so so hard to make him happy. He has multiple mental health problems (depression, PTSD, obsessive personality disorder and anxiety) and I feel like he's gone a bit downhill at the moment so that's why in my head I justify his behaviour.

Quite recently he got really angry at me cause I went out after work and didn't tell him, mainly cause he said he was going to bed early and I didn't want to wale him by texting/calling (he's a light sleeper) .He accused me of cheating, called me a liar and a slag even though he had no real reasons to believe I did that aside from his insecurities.

This was like a month ago and we made out he apologised and said just to tell him what I'm doing cause he gets scared but that he had no issue with me going out.

A couple of nights ago I went out, texted him everytime we decided to go to another bar/club and yrs I got really drunk and came back home quite late (5am). I went in the front room as I thought he'd be in bed but he was sleeping in the sofa and got super mad at me for waking him up called me inconsiderate said I looked like a fucking slag that had been fucked in the bushes

.. all cause I was drunk and my tights had some holes in from me falling earlier on in the night. Since then he's barely spoken to me but the few times he did was to tell me that I'm a fucking liar, I have no respect for him and that he's tired of telling me what to do. That going out till 5am is not acceptable in a serious adult relationship and that if he did the same I'd be upset (absolute lies cause as long as I knew he's safe I don't care if he wants to go on a night out and frankly he does come home drunk or even high so many times and I never gave him a bollocking for going out with the lads even if I didn't really like it).

I feel like he's never admitting his defects and always makes me feel bad about myself or like I don't feel like I can do certain things because I'm scared he'll get angry at me. Also he always threatens me with leaving me everytime I do something that's not to his liking

I don't know what to do, I love him very much and I'm scared because I feel like he's not a bad person, he's just been hirt so much by the world that he puts up all this walls but idk I feel like he behaves like a hurt dog that barfs/bites the person that's trying to help them after being damaged by someone else but this whole situation is having a massive impact on my already bad mental health.

Please I need some advice, some opinions. Has anyone been through something like this? Is there hope? Was I wrong for going out like that?

Thank you so much in advance
