In this type of situation, would you follow your boyfriend or go separate ways?

I've been dating a great guy for over 6 months now; he's 25, I'm 23. He's almost done with medical school & will be graduating in May to start residency. He'll be interviewing at various residencies other the winter months. I'll go along for most of them, when he goes to states out west (we're from NY). He will live at a residency for 3 yrs. He said "don't get too attached" to Colorado if we ended up there uming I'd follow him (the one I'm most excited about, as i hear it's a good place to live w/hiking skiing etc). He says he plans to come back to settle in the rural upstate NY in the adirondacks after residency & find a practice to join. I've heard him tell his family a few times, "I'll be back, I'll be back" when they freak out he may end up out west for 3 yrs...(if he doesnt go to Maine residency). He's a bit of a momma's boy, but I've been with worse. I don't see myself living permanently in the middle of upstate ny when it's a dead area, except for summer when tourists come.. He has this all mapped out & it concerns me a bit..Shouldn't I have some say? especially if or when we live together? I keep ending up w/these guys that have their life all mapped out, want this to happen, then this, etc etc.. Guys, when you're with a woman you love are there ever exceptions/ compromise? I try to take life one day at a time, but if he's going to be hung up on this adirondacks thing, I'm not sure i want it. I like his big family, they're nice enough.. but know they'd be on his doorstep every 5 minutes as they live there.. My family isn't close at all, we're all tered & i want out of ny hopefully permanently.. plus high taxes ugh! Thanks for input, both men and women.
