... a girl that i have feelings for messaged me yesterday and asked me if i love her and i guess she kind of wanted to talk to me again. 

The problem is, she hurt me alot in the past 4 years and we were friends and then no friends anymore and then friends again and so on and so on. It made me depressed. 

But okay now im not depressed anymore and i am pretty much over her but since she messaged me out of the blue i cant stop thinking about it (the reason why its affecting me so much is that i havent seen nor have i checked on her social networks and stuff since new years which is a huge step for me) and well how do i put it ... 

i cant stop thinking about if i should have just flown with it or if i did the right decision with telling her that i love her but that we will never be in a relationship and that we dont fit together. (Yes i never even dated her)

did i mention that she has borderline disorder, even tho she is treating that?
