What to do

When you’ve been with someone for years and are married with two kids but just aren’t happy. There isn’t someone else. I have a 6 month old and I’m a stay at home and literally don’t go anywhere. But anyway, I feel myself wanting more. This sounds so stupid but when I’m watching something on tv, i see how sweet and loving and kind the guys are and just wish my husband would be more like that. I see posts on Facebook of people bragging about their husbands and get jealous. I see people in public doing things as a family and I just want my life more like that. I’ve expressed my feelings to him and he says that’s just not him. I feel like we’re roommates and we barely talk once he’s home from work. On the weekends I go do things with my mom not him. We literally never spend quality time together. He’s always watching tv or something on his phone or he’s sleeping, working or just not home. What do I do?
