Happy but not happy :/

My bf and i have been together for 8 years. I have love for him and care for him, but i don't love him like i use to. He's cheated on me 3 times. The las5 time he cheated was with a coworker and he still works at that place. I broke up with him because i had enough of everything! But during our break up i was unemployed and still am. We have a 1 year old daughter and he's such a great dad. So the only reason im with him is because he pays all our bills and is a great dad. But im not happy anymore im actually miserable. Feedback please ppl
