I agree with what's been said, I think my girlfriend has a problem with my hobby. Sorry to hear that it's come up. But this is a good subject as many of us might end up in this situation sooner or later.
I've worked my *** off this summer to make extra money for my Ghia, 12-13 hour days 5 days a week, I ended up spending most of it on visiting my girlfriend in Canada. I don't regret it, but she doesn't understand that I have dreams...
Just a thought, I'd personaly go with the advice here. I kinda hope I don't have to use it, but I'm not sure if I can give up my dreams for someone. I can do anything I want in my life, and I intend to do just that.
