need opinions

I just broke up with my long time boyfriend. we have a 2 year old daughter together, we were together for almost 4 years. it was bad relationship we argued more than anything. I have our daughter bc I have always been the one to make sure she was taken care of. I don't want another man, honestly im happier just me and my daughter. I would rather maybe just go out to dinner with my girlfriends. all my past relationships have turned me against relationships. am I being stupid for not wanting to get into another relationship not only now but I don't see myself ever wanting another relationship. my trust is dead.
