give him time, if he says he wants 2 marry you, he does, dont pressure him into anything, all he needs is time, he'll decide when he is ready for that sort of commitment, jsut make him feel relaxed around you, talk about it in detail sometimes, don't ask him, wen is he going 2 propose, this wil make him feel un-easy, jus talk about it, how long do you think we'll last that sort of thing . . . Time is what he needs !!
