Some people haven't been abuse victims before and it shows dosent it....
OP this breaks my heart, I was in your position minus heavy drugs but in a very severely abusive relationship, I made excuses for his behaviour, he was drunk, he's depressed, it's my fault, he was angry, I was absolutely devastated when we ended (the only way I could break free was reporting him, him getting arrested and getting a restraining order in place) I didn't think there would be a light at the end of the tunnel and my life was over...
3 months on and even tho the case is ongoing still and there's a lot more to deal with and it is really hard, I feel SO much better! You never ever think you will feel better or get over it you feel your lifes over but I promise you when you leave its just the beginning!
I go out with friends, I have an amazing new job, no walking on eggshells, no more pain and now I realise what he did was so wrong, more importantly my son is a lot happier.
I really honestly know it feels like it won't get better and you need him but please please please battle through these hard feelings cos I promise you they don't last forever.
Another thing I will also say is you can't help someone who dosent want to help themselves
Contact womens aid, they will help you so much and also get you extra support too. It dosent seem it now but him leaving or u both ending will be the best thing that will ever happen to you. Woman's aid also have a survivors forum too which is really good, a lot of understanding ladies on there who can really help
You are worth so much more than this I really hope your OK, you got this.
