There are a lot of unknowns here (age, family, relationship history, career/educational aspirations, plans for children, etc), but overall, it sounds like you would like to wait, but you're no sure if you should. If that is the case, you may want to give it a reasonable time frame (whatever that is, but I'd suggest no more than 3 months) and if he hasn't decided that you and he are on the same page, commitment wise, then you'd have to make the difficult decision about breaking off from him. You did say that you had quite a few fights in the past; were they all about the same or similar things?
