If it was true love, his girlfriend would support him in all his hobbies and interests, and he shouldn't feel held back.
haha! good one. Too bad the guy is illusioned. In the end, I think he made the right choice, though! However, I might want to remind me of this from time to time, too, when I get lured by other things where I think they are incompatible with the true love I already found.
