I need to cut this girl out of my life soon but my attachment to her is making it hard

I have a pretty long story so I’ll try to make it as short as possible. Met this girl online on discord around November 2021 (I know) and became really close friends to this day. After a few months of texting, we started calling each other. We usually call for like 4-11 hours almost everyday. Because of this, I developed feelings and I ultimately told her how I felt around summer of 2023. She stated that she really appreciated it , but she said she didn’t know at the time and wanted to focus on school. She said that maybe later we can date and see where it goes. This got me hopeful for the next few years. So these next few years will fill my life with nightly companionship with a really close friend of mine who I’m attracted to. We have developed routines, inside jokes, sending each other gifts, etc. We know where each other lives and our family knows about each other. Everything felt good. I did ask if we can hang out and meet up at some point, but she said to bring friends. At one point, there was an orchestra that was showing an hour and a half from where she lives that I went to, but she wasn’t willing to meet up (this happened december 2024). This signified to me that maybe she really isn’t interested in me, but ofc me being dumb, I ignored it and was like “can’t force someone to meet u if they dont want to”.

During the months of May, June, and July of this year, she started being distant. I knew and confirmed that she met someone off a dating app and started hanging out with him. So I kept my distance, only texted her when she texted me and only called her if she wanted to. I tried my best to get over her during this time. However, During this month of August and the last week of July, she started contacting me a lot and initiated calls like before. I thought to myself, maybe it didn’t work out? However, I noticed that she pretty much contacts me and call me Sunday – Friday, but she told me she is busy hanging out with a friend on Saturdays. Just this past week, she just started posting on snap pictures of her with some guy. Right now, she’s on a trip to Florida with him (and maybe friends or family?). However, when nighttime comes, here she comes texting me and telling me “oh it’s so weird being in bed and not calling you” or “we have a lot of things to do when I get back”. I feel like I’m the emotional boyfriend right now while she explores the physical and romantic potential with that dude. I need to cut her off, but it’s hard when she is telling me things like this. I want to be the emotional boyfriend and more. I want to be the one she posts pics with. I don’t want to lose the closeness that we have, but at the same time it hurts because I want more. I’m surprised I’m not spiraling like before, but it’s just hard knowing that she is publicly showing him off while she plans on doing stuff with me. It’s like she wants the best of both worlds What do I do?
