I have learned my lesson about going back to ex girlfriends. It always seems different but then I always end up seeing exactly why I broke it off. Very rarely have I seen couples reconnect where it didn't turn out to be exactly the same way.
Not saying this will happen to you, just my experience. I mean I guess depending how long you have been done with high school that a lot could ave changed, but I am with Toxic. Ex girlfriends are ex girlfriends for a reason.
