I’ve been with my partner for over 11yrs and we have a 2yr old. For years we have had a turbulent relationship as he struggles with his mental health & i dont know what i’m going to get each day.. either the happy him or the angry/miserable him. His escape used to be taking cocaine and going missing for days on end with no contact after any slight bit of stress. He gave up drink & drugs a year ago but has had a few relapses since then. He blamed these outbursts on me & my character every time saying it was my fault as I stress him out which left me feeling confused about whether it was my fault. He struggles with caring for our daughter and finds the terrible 2’s tantrums too much leading me to solo parent and do absolutely everything on my own. A few days ago we had an argument, he said I only care about my daughter and not him, I told him to calm down to which he ran over to me and shouted ‘what did you just say’ at the top of his voice in my face, i asked him to leave me alone then he pushed me on the bed and grabbed my neck and told me to shutup. He left the room then I asked him to leave the house, he then ran back to me & shouted in my face telling me not to speak down to him. Luckily my daughter was not there but I felt really scared so i left the house & went to my parents & sent him a message asking why he did that to which he replied ‘Back in your place where you belong. Getting a bit big for your boots, try speaking to me like shit again and make me out to be a bad person.’.. he said he would only leave if i pay him £28k which I can’t possibly get, the most I can get on a loan is £10k. The mortgage is in my name but he has lived in the house & paid half of it for 8yrs. When I returned home, he had left but not taken any of his things which has left me feeling worried. I don’t want to live like this but i also dont any harm to come to him. I feel like I am a nice person, i try my best to be a good Mum and alls i have ever wanted is a happy life with my family but he makes it feel so difficult. It’s the same cycle every few months of these outbursts then him going missing for days. I feel lost and confused; I really dont know what to do anymore. Any advice would be appreciated.
