Idk what to do about my relationship anymore

He’s a good guy but he plays video games right after work until he goes to bed, he has barley touched me since I got pregnant (almost 18 weeks).. I’ve expressed these things to him and nothing changes even though he says he will work on it. I feel so unloved and unwanted, I wanted to marry this man. I woke up this morning and he asked why I haven’t been talkative or hugged him much or anything, it took everything in me to not break down and tell him I’m not sure if I love him anymore. I mean I know I love him but I guess I’m detaching slowly because I see no change. It breaks my heart but I think I’m going to have to end the relationship, I feel so unwanted and I feel ugly and disgusting. I’ve tried to think maybe it’s the hormones but I’ve calmly told him how I feel and nothing changes, he jacks off daily but won’t touch me... I beg him for sex and get nothing. He says he loves me and he’s been asking a lot what’s wrong but I just have been trying to make sure I mean it before I tell this man I don’t love him anymore and I want to leave our relationship. Anya device on what to do or how to break it to him would be nice. I’m crying as I write this post 😔 I just feel I’ve tried to do all I can and nothing is changing 🤷🏻‍♀️😭
