Getting a divorce

Ever since my child was born, my marriage has been getting worse and worse. Talking to my husband has been a daunting thing for me as I feel my voice could never be heard or he would get offended. I often feel I am fighting myself as he listens more to his family. I know I might be the first time Mom with lack of experience and all. But I also did my homework, I read from various resources, I got input too from my family, but whenever it comes to applying suggestions, always his family's ones come first. I know it might sound immature and selfish, to just take from this point to keep thinking about separation. But I just feel unvalued, disrespected and not trusted at all as a wife. I feel bad seeing my son to go through many episodes of me breaking down since the day he was born. I often blame myself for the decision of sticking to him and married him. I feel so overwhelmed and exhausted. There was a time we had a big fight and he said to me: "The only reason he still stays with me is because of my child." And when I said to him I want a full custody of my child if he wants to divorce me, he replied me with disdain, "You don't even have a financial capability to do that." I used to confide with him on my personal struggle but hearing those words, just awaken me and reminded me that I could not trust him anymore. I feel betrayed. If anyone ever go through a similar experience like mine, could you share what did you do to make yourself feel better? Thanks.
