Is it bad to break up with your gf just because?

Ive dated this girl for about a year and a half now. She treats me good, buys me clothes, listens to me, which is all awesome after growing up with a very neglectful family, yet i want to break up. Im not in love with her anymore, i dont really find her attractive, andi want to do things like travel and maybe move somewhere acrossthe country but she cant because of bills. Anyway my question is, is it bad to break up with someone just because your not feeling it, or because you want to move somewhere she cant
