I want to leave my husband

Okay, I'm laying all my cards out here and just going to hope someone has some advice. So let's start from the start. I had a rough childhood. Single mom, she was an alcoholic. Never known my dad. So I am pretty independent, sensitive and emotional. I have issues obviously because of it. So I met my husband at a school dance when I was 15. He was 18 but came with someone else, I stole him from them 🤣. Anyways, we were super in love. We lost our virginities to each other. Neither of us had ever been in real relationships before. So we learned it all together. We spent all of our time together literally. Never spent a day a part. His childhood was the opposite of mine. His family is pretty wealthy, parents are together, all that. Well, we bought a house together when I was 18. Not rent, bought. Then we got engaged, then I got pregnant and we got married. Fast forward now we've been together for 7 years. We have a 2 year old and a 9 month old. I do love him. And I'm trying so hard to make myself fall back in love with him, but we both are changing so much from who we used to be. We used to be the same person, we were obsessed with each other. Now he doesnt listen to anything when I try to talk to him, blames me for feeling like I do. He works 3rd shift and I work 1st to cut out babysitting costs. We only see each other on weekends and all we do is fight. He ignores me all weekend, acts like he wants nothing to do with me. And of course I have issues with myself. I'm over weight, and my body kinda sucks after 2 pregnancies so close together. He is tall, althetic, has abs. So naturally I'm insecure. I feel he deserves better and that I'm not good enough for him. I feel like maybe he would love me again if I was thinner. I talked to him about this stuff all the time and he never really seems to care much. He tells me to eat healthier and work out. But I'm exhausted from caring for the babies all evening and working all day and I dont have time to workout. As far as eating healthy, I can do that. I just have such a hard time cause I'm an emotional eater. I recently found out his family said they didnt like me and never wanted us to get married and wishes we would get divorced. And that's really hard for me because no matter what I always get rejected by everyone in my life. I try so hard to be nice, genuine, and someone everyone will love yet somehow I feel like everyone hates me. I'm to the point that I do think about killing myself and the only thing keeping me here is my daughters. I just cant help these feelings and dont want to be told that I'm pathetic or crazy if I tell someone about it because I'm not. I just cant help but feel like my life is worthless. I just wanna be loved and it seems like no matter what, nobody will love me. I've turned into such a cold shell of a person. I'm not happy. And I'm afraid I never will be. The only light i see in my life is my kids. I would never hurt myself because of my kids but i just hate feeling so helpless. I want to be happy, i want my husband to want me. I want my mom and his family to love me. I just am lost on what to do. I've tried everything already
