[Worried]

Hi,
This is my very first time on anything like this so this is a new experience for me. I'm not even sure when this posts where it will post but I am hopefully I will get some input.
I would like to get a feel from people as to what they think of the following situation:
I have been divorced for 6 years and about a year ago I meet the guy that I am hoping to spend the rest of my life with. The issue is he has two kids which he has 50% of the time (his ex lives handy so kids commute easily) and I have one child which lives with me 100%. This is all great everyone seems to be getting along and whatnot but the problem started once we talked about moving in together. The first issue was he thought I was going to sell my home and move in with him and I said that isn't really fair because my son and I wouldn't really feel like that was our home so I suggested we both sell our homes and buy a new home. He agreed after some deep consideration. Now the issue is he wants me and my son to move to his area. He thinks that makes more sense as he has the two kids (50%) and I guess I only have the one so . . . Anyhow it is about 25 min drive so it's not like he lives too far but my son really doesn't want to move. He is 16 and will be going in grade 11. I have offered to keep him in his home school and get him a car so he can commute but he's still not keen on it. Am I doing the wrong thing if I move with him or is it wrong to think my boyfriend should at least consider moving to our area? Or maybe I should just stay put until my son is done high school, another two years although I really feel like this is the guy and would like us all to spend more time together.
Any input would be appreciated
