Hi so I feel like my husband has gotten very distant with me, he leaves for work every morning and I stay home with our kids so all day I wait for him and when he gets home he only pays attention to our small baby but not me or other kids, and I mean come on I love that he loves his baby but I need attention too. There’s something in his eyes just the way he looks at me it’s weird. I don’t see anything there, I know that when I see him my eyes light up. And we don’t even have sex at all. I have to ask and he says no most of the time well all the time. And when we do have sex it’s like a routine same way same position all the time and it sucks. There’s no foreplay no kissing no nothing. I don’t know what to do anymore. He’s a good provider a good man a good father he just has soooo much good qualities but he just ignores me. I get no hugs no nothing. And I am tired of it. We’re supposed well we had talked about having another baby but how if we don’t have sex. But it’s ok I don’t want another baby anymore because I feel like this marriage is over. And I do talk to him about it all the time but nothing changes. I think he doesn’t love me and just won’t leave cause of the kids but it’s unfair to me, dont you think? He’s so quiet he just looks unhappy. I want him to be happy even if it’s not with me I’ll understand. I want to be happy too. I would like for him to open up and be honest with me. I am not happy. I am miserable
