My FP is basically also my only friend. If you can call her that. At this point I am more just her little sidekick that does whatever she wants. She called me and woke me up yesterday morning so she could ramble on for two hours about what she did the night before. And how bad she felt about it. She said she was on a date with this guy that she's been casually seeing for a couple months, While on this date she started talking to another guy and her date caught her trying to give this guy her number. So yeah, that's kind of messed up and she feels bad but the thing is, she does disrespectful and inconsiderate shit to me all the time and doesn't feel bad, never apologizes, doesn't give a shit. Like when she uninvited me from my own birthday trip overseas. Months later she was just like "oh did you feel some kinda way about that" well no shit I felt some kinda way about that. Then with this guy she was on the date with...last month me and her went out of town for the weekend only she never had any intention of spending time with me. She took me there so that she could drink all day and I could drive her to a theme park, which she knows is my favorite place in the world, to meet up with this guy. She led me on the entire day before finally we ended up there and she deserted me, left me cold and alone at night and didn't even once acknowledge my existence until I tried to be assertive and tell her I was leaving because obviously she just wanted to be alone with this dude. That blew up into a thing, because the guy immediately ran away and I couldn't even leave. So he rambles on about this for two hours yesterday and I  thought things were settled. And then she calls me again tonight. I seriously wanted to hang up on her, I could not believe she was bringing this shit up again. Now I have never been in any sort of romantic relationship which she knows, so IDK why she wouldn't like, just go to her sister with this. But she went ahead and rambled on again for 2 hours, as I was trying to not let her hear me crying. She didn't, she was oblivious to the fact that this was distressing to me. So I just comforted her again, I told her she shouldn't blame herself for messing up. That subconsciously she did it for a reason, either she was looking for an out or needed something she wasn't getting from this guy. That she should use this as an opportunity to learn and grow.  I think that helped her. Meanwhile, I haven't been able to leave my house due to crippling anxiety, paranoia, and intrusive thoughts. But what does that matter. I am the most useless insignificant piece of shit that has ever existed.
