I need advice please?

I've been in this relationship for about 3 years now. there have been some things in the past that made me not trust my girlfriend, not cheating or anything just little lies and things that bothered me. basically i was going through kind of a depression for a while now, but i keep telling myself shes perfect, because now that everything is done and over with she seemed to change, but i dont feel the spark anymore? i feel like its very hard to trust her even though i know she isnt lying, i never want to cuddle or even kiss her, the only thing i wanted was sex. i would never want to hold her hand anymore. but i used to always do things like that. now that we broke up its been a few days and i was a little happier. we talked and now i feel like maybe that would change. my question is will it? or am i just brainwashing myself into that it will get better. she is a great girl but i just cant feel the spark to want to show any affection at all, or did i just get over her and cant get the love back because of past problems?
