Hi Blossom20,
I myself am an alcoholic and drug abuser and find that part of the addiction is looking for an excuse for your actions weather it be your stressed at work, angry about absolutely anything or just having a bad day. It sounds like he may be quite possessive and have some insecuritys their that need to be addressed. Is he attending any counseling sessions ?, i found that I was hiding my emotions and as much as I kept admiting I had addictions I was still not acknowledging how insecure I felt about myself hence the drinking and lashing out. I cant give you to much advice as everyone is different but I would definitely go down the counseling route and also for yourself to make sure your coping OK. My mum done some counseling to try and understand me more but better to support her. Its not easy being in love with someone with addiction so make sure your looking after yourself! No matter that he is the one with the addiction you can’t let yourself be treated bad or you yourself with start to get mental health issues and will get yourself in a bad way. Hope all goes well and again sorry I can’t give better advice,
Take care.
