They dumped me but want to stay friends

Mostly a rant. The short version is that I confessed something that hurt them which led to them taking weeks to ‘think about what to do and how to feel” . they never told me that they had already ended the relationship in their mind. Meanwhile I tried to express apology through flowers and food while we weren’t talking. They kept saying we could talk but the time never came? Now after I confronted them they said there’s no way we can have a relationship and if I can still be there for them. They call me selfish for ‘love bombing’ and for not wanting to be friends after how they treated me for with silence and evasion… am i overreacting? Why would they expect me to be there for them “if they need me”? I gave them one final chance to do this otp and they ghosted me for the day. It didn’t even mean enough for them to pick up a phone and call me.

If you’re reading this, I love you but i can’t believe you did this. over text.
