Money and spending time outside

I currently have a fiance we been going together for about five years, together we have a 21 month old daughter and there is a possibility I might be pregnant again. My only problem is that my fiance doesn't take my daughter and I out to places because I don't think he likes to spend money, also he doesn't give me any money either, not even a penny. I don't work at the moment bcuz i have no one to watch our daughter n can't afford daycare. I just wanted to know would I be wrong if I were to split up with him? I'm getting tired and don't think he will change.
