My fp (21f) and i(21m) spent an entire week together for her birthday and things were going really well. on the last day of the week we went out drinking with this guy she’s talking too and i accidentally let her know that i had started cutting myself again. her reaction was angry that i ruined her night and she kept saying “why would you tell me that” like it sucked more for her hearing it than for me actually doing it. the next week she asked me to drive for six hours to help her buy a car and then drive myself four hours alone back to my place. of course i did because i’m incapable of saying no to her and then the next day she just starts ignoring me completely. she’s now dating that guy she was taking to and in the past when she has a new guy she will completely ignore me. once she ignored me for six weeks and then the day after she broke up with her then boyfriend asked me if i wanted to get together for lunch or something. our relationship is entirely non-sexual/romantic so i don’t really understand why it is that that changes things. i really want to end the friendship cause i can feel how terrible it is, but it just terrifies me to do so and i know that if she called me tomorrow i’d answer the phone and act like nothing was wrong or had happened at all. i hate that i’m teaching her that she can walk all over me in the friendship but i’m so scared of being left alone i’ll never change. she’s literally my only friend and i have no idea what to do
