How soon into a relationship should you live together?

am 22 (closer to 23) years old, and my boyfriend is almost 22. We have been together for a little over a year. We live almost 2 hours apart, and I work full time, making it impossible to see each other except on the weekends (and not even for the full weekend). We are thinking of moving in together by late next year some time (which will be about 2- 2 1/2 yerars that we have been together). I would like opinions on if that is too soon, if i am too young, or if i should be married first. if we didnt live so far,i'd be in no rush. i know my family will not be supportive in this. they will think i should wait until i'm married. i dont want to disappoint them, but at the same time i dont want to live 2 hours away from my boyfriend until we are married,. opinions
