Alright well there has been this girl who i have known for 4years, i hadnt seen her for 2 years, but i saw her last month and we have been talking often and seemed to be getting close, i liked her, she liked me a little, but there was always this other guy on her facebook, and i knew there was something beetween them, and i noticed she has been talking to me less frequently now, and then 2 days ago her relationship status changed on facebook, and shes going out with that kid, im not sure what to do, i dont know how its going to last..

but what should i do now, and what should i do if they break up?
