Just got out of a relationship. How do I keep her out of my mind and get my mind back in the right place?

This morning I played basketball with a bro and lifted but my mind was all on the breakup. I still went hard, but more like 80%. Then now I have a loss of appetite which is bad because I'm trying to bulk.

So far I've started meditating as of yesterday. I've also removed all pictures of her from my phone. But the issue is that a lot of what I usually do is now done half heatedly because my mind drifts to her.

Its oneitis. How can I fix this? Just keep living and it'll all be okay?

This part is me ranting and realizing how stupid I was for the most part. More of a way for me to get this off my chest rather than advice.

We were together for 9 months. Both we're virgins, lived next door in college, etc.

During that time we "broke up" 4 times and by that I mean her throwing fits and me not responding the way she wanted me to, her claiming I never loved her then she'd block me on social media and go to her room and cry. Within 12 hours she'll message me again asking if she can come over, then she does, apologizes, er fuck and everything's back to normal. (1st red flag).

I thought it was normal for girls to be emotional like that especially since I was talking to other girls at that time and I wqs her first relationship so I didn't do much about it. ( strike against me. Not enforcing boundaries or letting her know that's not okay. And putting up with that. All for the sake of pussy)

School ended 2 months ago and we go back to our homes. We live about 20 minutes apart but neither of out parents allow us to date so we meet at school when we do see each other.

Fast forward to this Tuesday night, she lets her dad use her phone and forgets to get out of Facebook. Afraid her parents will see, she blocks me, deletes her chat history and emails me letting me know. I know her parents are nosy like that so I understand. Yesterday morning I read the message and email her back letting her know cool. Unblock me on Facebook and things can get back to the usual. She wakes up and calls me, wish good morning and all the usual stuff. I tell her I'll call her back later because I'm playing basketball with one of my bros and then she hangs up. (2nd red flag. Very emotional.)

We finish hooping I call her but get no reply. After her morning class she calls me and let's me know her phone was dead because she forgot to charge it. Understandable I think and we talk for a while. Later that evening she gets off work early and comes to see me at work. Kisses me, says I love you, the usual, I thought.

Check Facebook and I'm still blocked. (Longest time I've ever been blocked). Few hours later she messages me, "love you. Dad has test tomorrow so I'm helping him study. I'll unblock you and we'll chat there after I finish helping him." Cool I thought and wait.

She unblocks me, sends me a screenshot of my Facebook and asks me why it says I'm single and says "okay I see. Bye, we're done." I tell her it's always been like that since high school because I have family friended on Facebook who if they saw me "in a relationship" would start asking questions.

She calls me selfish, and says fuck you. I tell her to stop being crazy. She says "I'M ALWAYS GOING TO BE LIKE THIS. FUCK YOU. HOW COULD I BE SO STUPID. I SWEAR TO GOD WE'RE DONE." (Red flag x10)

I remember Archwinger's "Don't communicate, leave" and realize I've been getting played all this time. (Another strike against me. For being stupid).

I decide to go to bed. Later today around 10 she calls me on her way to class. I answer, say hello but get no response. She calls again, and same thing happens. Third time she calls I don't answer and she texts me "That's the last time I'm calling, I swear to God." and haven't heard from her since then. Funny thing is whens she's upset with me I'm blocked from all her social media but now I'm just unfriended which communicates to me that she wants me to message her asking for us to talk and basically ask for her back, which thanks to Archwinger is not going to happen. In that sense we're over, but if she asks me to fuck I won't say no. (Bad idea?)

I'm expecting her apology text within the next 3 days where she begs for me back again. If it doesn't come I don't care, like wise if it does (but if I didn't care would I have wrote this?).
