My friend's new bf is trying to carry on a conversation with me on FB but even I have to say it's a bit too oddball even for me. I know means well but I wish he were more like you guys, he'd be easier to talk to at least.
Commitment is part of it. I think it has to be two people who really want to be together despite the obstacles. But situations like that are only temporary and resolve themselves one way or the other in due time.
