Hey Miss Murder can I...

He's baaaaaaaack!

Its much too complicated to explain the situation, but basically a friend of mine is back in my life. He had a really shitty girlfriend who wouldn't let him talk to any girls, so for 4 months, I've had no idea where he was (oh yeah he lives far away, like a plane ride away) for quite a while. This isn't the first time he's disappeared, its the 3 or 4th time. Never for the same reason either, girls, school, didn't pay his phone bill, etc. But each time this happens, I welcome him back with open arms.

Is this unhealthy? I know its just a friendship, and I'm not looking for anything more (since there are a few thousand miles in between us), but is it unhealthy to even attempt a friendship with a such a flake?
