This guy really fancied my mate an she likes him now too, but ever since he knows he would have to convert to be with her hes been distant. They have been talking recently but hes seein others an arent together but he always saying how nice my mate is and gets annoyed when people say stuff like my mates getting marriage proposals and he said, 'let her get dragged down the isle then' an the next says she is kind, but then says summat hurtful. Hes upset her a few times as he kind of just blurts stuff out. He says hes not scared of his feelins but acts strange.

Whys he like that?

Maybe he's upset and dealing with the fact that in order to be with her he'd have to convert to her religion (I assume converting to religion is what you're talking about when you say "convert"). I mean, to me, it sounds like he likes her and possibly loves her, but can't or doesn't want to convert. So, he's feeling bitter whenever he hears about her marriage proposals or her being with other people. He's also probably dating other people to get her out of his head.

In my opinion, your friend should just move on. If this guy really liked/loved her and wanted to be with her, then he'd have no problem converting, no matter how hard it would be for him. Many dating couples and marriages have this problem, but in the end, love conquers all and the person converts to satisfy their significant other or to satisfy their significant other's family. That's just how it is. But maybe he can't convert or doesn't want to, but at the same time, really wants to be with her. But still, even if he doesn't want to convert, if he loved her enough he'd do anything to be with her. Which means that he obviously doesn't love her enough.

Or maybe, he's just acting weird. Maybe he doesn't feel bitter over wanting her. He could be acting weird for no reason or for a different reason. Either way, you won't know until you ask him what's wrong. Ask him why he's acting so weird and then ask him if it has to do with your friend. Good luck to you and your friend, hun. =]
