Most Helpful Guy
Who knows what his intentions are as far as his vacation... I think if I were in your shoes I wouldn't wait around for him if he isn't ready to commit on any level, if you have other guys who are interested in you and who ARE ready to start taking the relationship in a more serious direction, don't pass up on those opportunities in hopes that this other guy will come around. Maybe he will, but then again you might be waiting for a LONG time while he does his own thing.
If you really like him and he treats you well and you don't mind laying low for a while, that's fine, but don't let too much time and too many opportunities go by because you're hoping that he's going to do what's right and properly date you.
How long is he going to be gone for?
