How far is too far to get in contact with a friend who ghosted me!

i (20 F) made close friends with a girl (F 21) about two years ago now. We both were working at this bar and grill in our hometown. We were the only two girls who were close in age and we instantly connected. After a couple of months we became more than work friends we became best friends. I would spend multiple nights out of the week at her house, we took trips together, shared every special moment with each other and every bad one. We really became each other’s greatest friends in our small town. The fall down really starts to happen when she introduced me to her brother. My friends brother (19) first saw a picture of me on instagram at one of our girls trip. He screenshotted it and made a big deal about how attractive i am. At the time i was in a relationship and i was not that kind of person, also no offense to the brother but he simply wasn't my type. Months later im single and the brother comes back to our hometown after basic training. we meet in person for the first time and still i was not interested. Long story short a couple weeks later we both get really drunk and we end up sleeping together. I saw it as a simple drunk night that would never lead anywhere. I was getting ready to go to college 14 hours away from home and he was getting stationed about 4 hours away from where i was going. He did not see it this way. he saw it as a long distance relationship type of situation i guess. all i know is one second he was just my friends brother the next he was cuddling, kissing, doing all of the pda in front of all of our friends and his family, having conversations of what our future would look like. Me, being very young and fresh out of a toxic relationship i fell for him and i fell hard. boy did he make a HUGE fool out of me and teach me i need to trust my gut. even longer story short he ends up being the stereotype of every military man i have ever met he has a girlfriend he was hiding. not only were they dating, he was seeing her every time he wasnt see me , she had his location which she used to find me, the brother, my friend, and every single one of my friends who knew we had something going on. That is when we found out that the girl was pregnant. SUPER freaking pregnant, 6 months pregnant, which happened to make it line up that he got her pregnant and then went off the basic training. it was very public and humiliating moment. Everyone i knew watching me put everything together. I wouldn't wish any of it on my worst enemy. It was actually a really rough patch for me. Not because of the guy, but because it was so incredibly embarrassing at the time. I never expected anyone to pick sides especially because he is my best friends brother but after everything went down i got cut out of the group. Everyone decided i was ”dragging it “ and the brother was a man taking care of his responsibilities. I lost all of my friends at a time i was already really embarrassed. In a moment im not proud of i reached out to the girlfriend and we had a conversation over message. it was the usual how long did he know, did i know about her, did she know about me type of conversation i guess you have when you are the other woman. this conversation led to the worlds biggest plot twist. i did not know about the girl but she knew about me. he was honest about me but painted me a his sisters crazy friend who he wanted nothing to do with which makes no sense because one screenshots of him talking about me and because we slept together. why didnt the girl care more about me you May or may not be asking. Well i will tell you because her baby wasn't his. they were dating they both Cheated and because he wanted better military housing and she wanted to be taken care of they were planning to lie about the baby and say it was his. i obvi never speak to this guy ever again but after talking to my friend his sister she says were good! We make jokes about the situation and stay friends as if nothing ever. Fast forward months later to the day before i leave for college we spend the night having dinner making memories crying about me leaving struggling to say goodbye but we say we will see each other for thanksgiving and i leave. The night i arrive to my college town she text me asking me how it is and thats the last conversation we have until about three weeks later we have a phone conversation where we talk for 5 minutes before she hangs up because her boyfriend needs her. That was last august and i have not heard from her since. It broke my heart every time she would ignore me but i accepted that the thing with her brother was deeper than i thought or i had done something else wrong that she did not want to talk to. I was in a new city hours away trying to make new friends when the one i really needed wanted nothing to do with me. I accepted it and started to move on. That was until i learned she had been telling people in our hometown that we were still best friends, that we talked all the time, and that i was doing so well. She made up this whole Friendship that simply was not happening. then she started posting pictures of me on social media that were months old but she didnt even follow me back. now im simply confused. At this point i do not want to be friends anymore but after a year of this extremely weird behaviour i wanna know what is going on Or if im being overdramtic and i need to just let it go. I am sorry this post is so long but if i could get any advice about what i should do it would be amazing. Thank you!
