Am in love with my ex girlfriend friend,, what can I do?

I would just be friends with her for the time being and see where things go from there, Remember a Ex is Ex for a reason..It takes time for relationships to heal before you even think about getting back together with you Ex partner..Sometimes getting back with a Ex is the wrong decision that we often make than after we get back together we find out that things have never changed..I found this out a few times and it cost me to have a classring stolen which was priceless to me cause my late grand-dad bought it for me..So you wanna think twice about this situation
