hit it and quit it
jk, i guess give it time. stay as friends for now until you really see you guys can move forward. like the others have said "2 weeks is too short for 2 years".
PERHAPS it could just be a break between her and her ex. and while she's having that break, she's with you, comparing you two. i hope all works well with you though. whether you end up as friends or together, good luck! don't rush it!
