Shes been hurt....so shes afraid of getting into anything serious right now. I can see why....... I mean she was with a guy for 3 yrs and he just took off. So now shes probably skeptical about men and think that one day you might turn on her. The only thing you can do is to be there for her. Reassure her that you want to be with her and that you want to take things slow.......and then take things slow. If she doesn't feel comfy with this ....then maybe its best to move on. If she is ok with this...then give it a shot....
