Shared Spotify account with EX-GF and group of friends (What to do?)

My ex GF broke up with me 7 months ago and it hurted me very bad, she didnt gave me a reason and deleted me from her life like I was nothing and she's now with her EX BF right after she break up with me. She's hiding it but everyone knows.

We are no contact for like 6 months and in January now the subscription of spotify will renew, it's me, my ex GF and 4 friends. I felt bad cancelling it because of the other 4, so I posted in the old group we had to see if everyone wanted to remain in the spotify, everyone said Yes including her. I asked everyone to send me the total yearly of their part but they will only do end of the month.

What is triggering me is that I'm being really nice about it, she made me suffer a lot and I dont know what to do, I dont know if I simply remove her and pay for 2 persons for a year without her on our spotify, if I simply let her there, but I kinda dont want anything from her, not even her money, I dont know what to do shen she sends her part to me, part of me dont wanna that money, part of me dont wanna her to be included, even though I'm doing just fine, I dont know if I'm acting ok just letting her pay and be part of it.

Give me some insights please
