Should I(17f) confront my friend or just let the friendship go?

(I’ve posted on here before but I really need advice)🙏🙏 I’ll use fake names for confidentiality. For context, me, “Calliope” and “Rachel”(Both 17f) were quite close the last few years of secondary school; when we left, me and Calliope ended up at the same school, while Rachel went to a different college. Since we didn’t see each other as often anymore, we made Fridays our day to hang out; no school the next day and we were all free so it was the ideal day to always meet up.

At first it was fun. Rachel even sometimes brought her boyfriend “Ashton” and that was fine; although even then sometimes she’d just leave with him without telling us but we didn’t take much notice of this at the time. But then Ashton’s best friend “Greg” started coming to the hang out on Friday; I did know this guy beforehand but we weren’t insanely close. Rachel kept trying to set me up with Greg even though she herself had said she didn’t rlly like him. Eventually, she set Greg up with someone she had met from college, Becca.

Since then, Rachel would normally bring the other 3 as well. The problem? Greg and Becca clearly didn’t like me or Calliope nor wanted us to be there. They made it very obvious with dirty looks, cold energy. It was very obvious how awkward it was; Rachel can see it, but she just instead blames us for not “trying harder” to get along and making it awkward.

There’ve also been times where they just abandoned us when hanging out. One time, she barely hung out/talked to us the whole night(like actively moved to tables from us with the other three when we were hanging out idk why😭) then when we were waiting for them to leave together, they had just ditched us to hang in the park without saying anything. When I texted, she ignored it until they had already gone, saying she thought we alr left which I know she didn’t. She apologized, said she’d make it up to us; but her behaviour didn’t change. That night was the ticking point, so we stopped going to our usual hang out on Fridays cause it wasn’t rlly fun anymore and me and Calliope would just spend most times by ourselves by the end of it so it was pointless. We just started to hang out on Fridays as a duo. I’m pretty sure they still continued to hang out on Fridays after that, fair enough.

We saw each other last Friday, the first time in a while. She called us up to hang out because she was “lonely” . We went, all had a good time, and she specifically told us: “Keep next Friday free.” So the next Friday, we notice her in the area and go to surprise her and see her there with Greg, Becca and Ashton. We then kinda realised she only rlly called us up last Friday cause Greg, Becca and Ashton weren’t free. We then started to realised for the past couple months only really calls us to hang out or chat when the other 3 aren’t available like we’re the backup option, the “booty call friends.”😭

I’ve asked advice from some ppl and they’ve said the way she treats me shows she doesn’t respect me and it’s not worth staying friends with her; but we’ve been known each other for years and I do still value our friendship. So Reddit, what do I do? Is it worth confronting her about this and seeing how reacts and if she actually reflects and changes? Or is it not worth it and perhaps I should just let the friendship go now? Or am I making a big deal over nothing?
