I'm still texting a girl who cheated on her bf with me
How long did she wait to text you?
I don't know, I guess the next day
I think that you should try to distance yourself from her. It is wrong to keep texting with some that cheated on their boyfriend with you.
She just a friend with "benefits". Not reason not to meet her again and have sex.
This person is toxic, and you would do yourself some good to stay away from her.
