I was in a similar situation (hometown is Leeds, university is in Newcastle, so 90mins on a train) and it didn't mess up my independence. I see it as a good thing for two reasons: I'm far away enough to get my independence, but I'm also close to home if I need to/when I do go back. As everyone else has said, choose your favorite university and go with it! It's a learning curve for them as well and they will miss you, but I doubt they'll be up to see you every weekend. As RovingFish said, agree to visit them/them to visit you every so often; but also remember to Skype/Text/Facebook/Call them will you're away too!
