Should I keep trying or divorce?

A lil back story. His dads an alcoholic, his mom cheats, and she also hates me. She will do petty stuff in front of me and the second her son comes around she acts all sweet. I could care less what she does. But my husband doesnt defend me. Its gotten to the point where I dont even talk to his family and I dont want that for him. When I met my husband I was so in love. But I'm starting to realize I wasnt treated the wa I should have been. I've been with my now husband for almost 6 years. Married for 2 month. I know it hasnt been that long. But ever since I met him I was madly in love. He was my very 1st boyfriend and everything. And of course i wanted to marry him and have kids with him. Now that we are married I am realizing that I dont think I want to have kids with him. Because I know what I want in a relationship and I don't get it from him. I want somebody better for him. I could care less about me. I'm not sure what to do. I don't wanna hurt him because I love him. But I don't wanna have either if us suffering. We have talked about fixing "us" for years and it doesnt work.
