Not happy😔

Sorry for the long post but I have to let myself out..

I have no one to talk to about my situation so I though I can always share it here and get some advises. I been in relation with my husband for almost 3 yrs and got married October 2017. The beginning of our relationship was perfect, he was caring loving and talked about giving a better life to me and my 2 kids from previous marriage. Not to mention my last marriage was arranged by my parents(I'm a middle eastern so arranged marriages are normal there) lasted for 7 yrs and got divorce going against my family... so long story short now I'm not happy with him. I'm currently pregnant, he dont take care of me if I'm not feeling well, doesnt bother to get up and cook for himself or even get the kids to school. I have to do everything, house chores, taking care of kids, taking care of him, he is just soo lazy and doesnt help at all in fact gets me up in the middle of the night to cook him something. Our sex life is miserable also..like I said beginning of our relationship he was good. He made sex life more enjoyable but now we barely have sex probably twice a month which is always about him. He wants BJ and wants to orgasm through it meanwhile he dont put no effort for me at all which always leaves unsatisfied. He dont give me oral but dsnt even use his finger 😑but wants me to do all he wants while giving him BJ. I know alot of you ladies are going to say leave him etc but I cant. I have no work experience and currently pregnant most important i dont have no friends no family to support me and no money, I depend on him. My family is against me and disowned me because of this relationship. I have tried talking to him but he just argues and things get worst which I dont want my kids to go through again because of my last abusive marriage. I feel miserable and depressed! I dont know what to do or how to change this man. I loved him alot and believed him with all my heart but now that love is fading away because of this. And about the sex, obviously every human needs it. Hes selfish about himself but dont think about me. He doesn't know how I feel after losing everyone only for him, I dont think I deserve this😑 I dont think he deserves me..(FYI I know he isn't cheating) so please dont go off telling me hes cheating..

Thanks for your time. 😊
