How can i stop loving her...

So 2 months ago, my gf broke up with me, she cheated and said she loved the other guy more than she loved me

2 days ago she sent me a message that the guy broke up with her and feels like is she had known she would never ended things with me.

Im trying to be friends now, we've been texting for 2 days now, she even told me about a guy she met on tinder whom she's getting interested in, i feel like he's a rebound however since she's only been dumped on wednesday a week ago and they met on the saturday after. I dont want her to get hurt ya know, i never would want her to get hurt, all i want is for her to be happy, problem is, i wanna be happy myself too, i still care too much about her, its hard to stop caring, i wish i could just switch this off and just be her friend like we both want to be, but all i feel is hurt
