I am at a dilemma

I am 27 f, I fell in love with the father of my two girls while in high school, our love tale has been a long one, I am from a traditional financially very stable Arab family, but my family moved to Britain and gave birth to me in Liverpool. So technically, we still have these Arab/Muslim traditions. I was my parents favorite.

My BF was British Christian, so my family was totally against our being together.. we both were in love, we didn't care what they thought about us. After high school, we went to the same college, and after graduation, we decided to run away because the pressure from family was too much, both mine and his. That was how I left my family and forsook all pleasures for James. We migrated to one of the European countries. We have been here for five years, then he got a new better paying job. Everything seems normal and going well for the first five months, even though he has been showing some form of provocation towards me sometimes. In the sixth month he was posted to another department, then things got worst. He would want to hit me at every given chance, he stays out late, makes some suspicious call and most times when I try to make love to him, he acts like I irritate him. I tried raising my concerns with him, but he is always quick to brush it off.. so I decided to hire a professional to hack his phone after getting into his WhatsApp and got a genuine one after three trials. I discovered my partner is seeing some other lady now, telling her he is not married, Even one time I happened to listen to his call, he told her that I was actually forcing myself on him, and that he is tired of having me around. I kicked him out of the apartment, I regret turning my back on my family, Even when my mum died, I couldn't attend the funeral to show her my last respect because of him. But our daughters still miss their dad, what do I do?
