Input: Just some background me(M20) and her(F21) Ill call her L. We've been best friends for 2 years to the point that we hung out everyday, we both suffer from demons as Ive struggled with treatment resistant depression and anxiety my whole life and shes struggled with Anorexia,PTSD, Bipolar disorder, depression, and anxiety. We were both at healthier points of our lives when we met and draw healthy boundries when it comes to our mental illnesses affecting each other, we've always had open communication and been honest about everything.  


About 10 months ago L got in a relationship with this girl she met on tinder. They were happy for a month until L's girlfriend started fucking around and decided to "break up" with L because she wanted to be single. Over the next 9 months this girl remains a constant part of L's life and becomes extremely manipulative (gaslighting L, blocking L when they fought, making L feel like it was her fault they werent together) It caused L to spiral, her anorexia flared up in full force, she began lying to me about her eating habits and purging until around November when she finally realized she needed help and admitted everything to me and I was super supportive and told her id be there for her no matter what. L tried cutting her ex out of her life but refused to block her entirely because her ex also had an eating disorder and L felt she needed to be there for her. She was doing really well and the only social media she had of her ex was on tumblr until a few weeks ago, her ex posted on tumblr saying she cut herself because everyone leaves her, so L immediately feels she needs to reach out to her ex. This is when the troubles started, L knew I wouldnt be happy and began shutting me out telling me they only talk when her ex is having a hard time but it turns out theyve been having regular conversation daily.

Cut to today L tells me shes dog sitting a mutual friends house tonight and we should sleep there. Then later she tells me tomorrow shes going to have a lady friend over so I should leave and give her privacy. I ask her who is it and she tells me dont worry about it so I straight up ask her "is it your ex" and she says "no no no never." A few hours go by and we get to the house, we decide on pizza for dinner and she decides she wants to go to the liquor store, she comes back from the store and says while half-heartily laughing "hey so i lied to you before someone coming over tonight so I got them beer" I ask "who is it" no answer "L whos coming" she responds "ex is coming Im going to get laid dont make a big deal out of it" so I tell her "Im just letting you know I just dont even want to hang out with her so if you could tell me when shes close Id appreciate it, Im sorry if you think Im making a big deal out of this like I understand you want to have sex but, your my best friend and she hurt you so much for so long that I cant just shake my extremely negative feelings towards her, so Im going to have to excuse myself, Im also really annoyed that you lied to me and feel like you need to hide things from me but whatever youre going to do what you want, I hope you have a good night and enjoy yourself Ive just had a really shitty day mentally and Id like to remove myself before it gets worse." she begins to get really annoyed "whatever just leave then like why do you care its none of your business she hurt me but I want to have sex and I know what Im doing this is my life and if you dont want to be here then leave honestly youre being so dramatic just leave." so I get up and leave. So AITA?
