i do, i don't

I have been with my husband for 3 years, got married in Jan. but he makes me so mad I sometimes cry myself to sleep bcuz I don't know what to do. I don't want to get a divorce because I'm so young and I would just feel worthless afterwards. I don't know if I love him anymore. I do sometimes, but then he goes and does something stupid and behind my back, and then I don't feel anything but regret. I want to stay with him, but he won't change.

any advice......
