I’m hurting

I think I’m falling out of love. My S.O has been cold to me most days even though throughout the day we will have a few laughs. My daughter (who isn’t his but they treat each other like father/daughter) loves him so much. I feel broken and I have nobody to turn to. I don’t want to end things even though it’s feeling like it’s going to. I want him around. I want to be with him. I want him as he is right here in our lives. But I feel as if he doesn’t truly want to stay. And I am not forcing him to. He denies my advances. I’m heavy and I don’t feel comfortable in front of him most days and if we do have sex which is a rare occurrence nowadays I can’t be naked. I feel disgusting on top of him and I lose all my self esteem and I get completely turned off. I’ve just done my makeup and just sitting on my bed in a robe while he showered, got dressed and left. I feel as though I’m going to start bawling my eyes out. I know I have a gorgeous daughter to live for but this post isn’t about her. It’s about him and I. I tried explaining how I feel to him but he doesn’t really understand. We’ve fought. We’ve sat down and had multiple conversations. And I tried. I tried to be happy and smile like I used to. Goof around, be my normal self. I feel as if I lost like 50 lbs he might actually want me again. Idk if anybody will respond but I’ll hope.
