Need Help with an Ex-Friend (long i am sorry)

hello! I know this is mostly for romantic type of relationship issues, but I have a friend issue. Lets call her Jenna. Jenna and I became instantly close at the start of college. Inseparable. We had so many things in common it was kinda crazy. We became instantly each others “best friend”. We planned to make trips, live together everything. Then all of her sudden after 3 months of hanging out, she finally dipped her toes into boy realm and things started going south quickly. She flaked on plans. Long, extensive plans she flaked. She became infatuated with a boy insanely quickly, and she shoved off all plans with me and another friend all the time. It became insanely difficult to be her and friend and support her when all she wanted to do was talk about her new boyfriend, and its like her personality shifted. Which is ok! But I spent many nights depressed over what was wrong. Fast forward to spring, she still with said boyfriend of that freshman year and seemingly for being so close for 6 months at this point I find out through him she is on a crap ton of medication.

Depression and anxiety medication. She never once told me this, and I thought we were insanely close. Even when in groups of people she would always latch onto me and other people would tell me after saying “Jenna would not leave your side”. It was an odd friendship. I questioned to her why she wouldn’t tell me shes on all this medication (I told her some secrets about my family and myself, so it once again seemed unbalanced) as to I thought we were closer.

She point blank to me “since you don’t take birth control, I figured you would judge me for taking pills for anxiety and depression”. I was in shock. I said “how does my choice not to take birth control impact my opinion on other peoples right to take whatever they want??”. Clearly, there was some miscommunication problems then. This was not even the first red flag, but one that first resonated with me.

A couple weeks later, I told her I couldn’t go to a beach thing with her due to my Dad having some issues with his illness (he has stage 4 cancer..which she knows), and texted the other people involved that I “bailed”. I was so mad.

I started slowly detaching myself from her for a bit, realizing her true colors. Between the flakiness, and me realizing we are really not that close . just because we hung out all the time doesn’t make it a healthy friendship. I started questioning what a “friend” actually meant. We both though signed a lease for sophomore year to live together. So I tried to keep it civil and amicable. I should have spoken up about my problems with our “friendship” earlier, yes I learned from this now. And won’t do it again. Following that fall of 2018, we both were doing different things and only hung out when we were both in the room together. I started dating someone and she got mad whenever she tried to make plans, and I told her I already had some with my boyfriend at the time. I never once flaked on her. Not like she did to me the previous year. She didn’t tell me she was annoyed until months later, which didn’t help.

Fast forward to that winter, I got a text from her saying how much she loves living with me. That didn’t correlate to her asking me about living together the following year. There was a whole miscommunication amongst that. I ended up signing a lease with another friend for a different house, thinking Jenna had other friends to live with. I was wrong. I apologized to her for miscommunication multiple times and asked if she wanted to talk about it,she said its fine and no. She then proceeded to not speak to me for 3 months while living in the same room and removed me from practically everything on social media. She set up an appointment to discuss roommate issues (which was just friendship issues) and I asked her why she couldn’t just tell me this in the room for the past three months, she had the problem. I didn’t. She responded with “I hate confrontation”. How do you operate with a person like that??

I apologized again for MY miscommunication with living together for the following year I owned up to that. She asked if things could go back to how they were and I said I think its too late, but I do still wish and want to be friendly. She didn’t like that answer. We both changed and shifted. I tried making small talk after that in the room, but she did the minimal amount. It was clear she was still pissed and or annoyed. I did all I could. I truly did. I was honest. And civil.

Just found out she blocked me on facebook..of all social media sites. I get the message. I just thought blocking was a bit intense. We have a crap ton of mutual friends and am concerned she is trashing me to all of them for the past 6 months. Everyone asks what went down between us and I say we just grew apart and things shift. I have no hate towards her whatsoever. I am honestly better (and she might be better without me in her life too) that her in my life (she got into drugs and alcohol heavily after we shifted, and I am not into that) I just have been hoping this doesn’t affect my other friendships but I have ZERO control over it all. ZERO. Besides being myself, and learning from my mistakes.

How do you stop caring what other people think??
