18 y.o. girl and 25 y.o. guy dating?

I'm 18 and I'm very mature for my age (I pay my own bills, getting ready to move out, etc.) I met this guy on Tinder and we've been on a few pretty sophisticated dates so far. Neither of us mind the age difference because we have a lot in common and we just click. Do you think 18 and 25 is too much of an age difference?
