Should I reach out?

Hi guys.

One of the friends I'm having issues IRL is someone I know since we were kids. Let's call her Mel. We meet when we were 9 yo (were share the same year) and we became "BFF's" by the age of 14.

Mel and I have a very strange friendship. I always considered her a soul sister, and she used to claim the same for me, even tho she have a blood sister. I always thought our friendship was special, so the loyalty I had to her I never have to anyone else up to this day. First crush, first bra, first period, all the changes we were there for each other. I actually broke up two relationships because I knew she was in love with the guys and honestly I didn't care about them at the time anyway so felt like a favor to everybody. She never asked me to, I just saw them flirting when we went out and on social media too. Before we're BFF's she hook up with a guy I was hooking up first. She cried, I didn't care. He was a dog, she did me a favor. I was no saint either. I once hook up with someone she liked, but I'm my defense I asked for permission and she granted. 🤷🏻‍♀️ But nowadays she forgot that part, and she forgot what she did to me. A lot of history.

Anyway, I was always the one reaching to hang out, I pay for travels and amusement parks because I wanted to share those kind of memories with her and she couldn't afford at the time. I loaned her money when she needed to treat her dog and never asked back (and I never will). I was always there when someone broke up with her, when she had family issues and because all the bullying she suffered at school. Yet, when she got a job, she just forget about me. I see all the partying with whomever and just stop replying my messages. It happened a lot when we were growing up but around ten years ago she ghosted be for about six or seven years, and out of nowhere she reply a message I sent years prior. She accused me of setting her up to cheat her boyfriend. Like, she said she thought I talked to a guy to hit on her so she would cheat her BF. I was like "whaaaaat... I don't even have a reason for that". Anyway, she apologize but at that point I started with an amazing psychoanalyst and begin questioning all my friendships and that was a red flag for me. But I'm very needy for family and deep connection, so I experiment new boundaries for us because I never had that kind of connection before nor after her. She really was my sister... Then it all started again, she's just ghosting me. I see her interacting with people but my messages are ignored. I know she's not my friend, never was. I'm ready to let her go despise my hurt and not having anything to replace this relationship.

My question is: should I reach her to have some answers, or it will only open a door for fighting? Because we never actually fought before, she just disappears. I was thinking on asking if I did or said something offensive to her or something like that, because I never understand why she keeps doing that to me...

Thank you in advance.
