Hi! I (30F) and my husband (31M) have been in a relationship since 9 years and married for almost 4 years, with an almost 3 year old kid. For most part, the marraige is smooth but I am very unhappy and depressed because I think he doesn't love me anymore.He isn't an expressive man, (although he is quite expressive with his friends) and constantly belittles my emotional outbursts.He doesn't cuddle, nor touch or even look at me romantically. He values and prioritises everything above me. He only wants his "me time" and treats spending time with me as a chore. He will never say a romantic word out of his own mouth and even if I put words in his mouth, he will laugh at it and feels silly repeating it. I have been clearly telling him how much this affects me and what I want from him and how he can be better, every few days.I feel like I am the only one in the relationship, like I am unwanted and the burden of carrying this relationship falls only on me. We both take care of each other as responsibilities very well, but there is zero love or romance. We haven't even had sex in almost a year. Everytime I bring these things up, he promises he'll try better and change his ways but he just doesn't. He has very hectic work schedule (1 pm to 10 pm) but the rest of the time he spends sleeping, playing games on his phone and having his dinner while watching tv. The only couple time we have is watching tv while having dinner where we ask about what each others' day was like and that's it. We sleep in the same bed but he doesn't even touch, he cuddles with his son and sleeps off. I am tired of living a loveless life. He wasn't this way before and whenever I say this, he says that you knew the kind of man you were marrying. I think this began after I gave birth to our son, where I've gained some weight, which I've tried to lose many times, unsuccessfully. He makes me hate myself and just destroy my peace and confidence and I hate the way he makes me beg for bare minimum and just doesn't change. I am exhausted. Where have I gone wrong? What do I do?
p.s. I'm confident he is not having an affair or anything of that sort.
