im pretty sure i have lost any way to contact her, when i saw her facial expression the second i said hi, and we recognised eachother, she looked like i had caught her in the middle of a crime or something, or just caught her off guard in a big way. i tried to make small talk, but she ended the conversation by saying "fuck that, disability (pension) for life" after i said i'm studying at the moment. i wanted to be able to get the message across that i feel awful for the way that i ended our friendship/relationship, but although this sounds bad, i think the damage is done now, and she would have so many defence mechanisms that i don't know what her reaction might be if i tried to bring it up.
this is the second time that something like this has happened, last time i fell in love with a girl while i was on a large dose of mdma at a bar. she wrote her name on my arm, and i was scattered when i got home so i took a bath and it came off. a month later i bumped into her and her friend again, and i tried to explain what happened and i think she went to the bathroom to cry or just avoid me, then i saw her about 8 months later recently, we made eye contact for half a second, then i saw her shrink away, so i just rode away because of her body language, but i wanted to tell her that i felt awful about what happened.
live and learn i guess
