so i was hanging out with my xgf earlier this summer and one thing led to another... long story short when i went home the next morning she texted me "we should def be fuck buddies this summer." now she has a history of psychological issues, so i was skeptical at first, but after almost a month of no crazies i started to fall for her again. biiiiiiiiig mistake. now she's back on the crazy train and i don't know how to tell her that this is my stop. any suggestions? cliffs: crazy xgf wanted to be fuck buddies and now i'm in too deep. help?
