Feeling down..

So whenever my friend and I talk about what happened (sex!) to me and the guy I'm seeing (not boyfriend) she always tells me I did it wrong and how unholy I am (she is Christian, I'm not). I can't help but to feel guilty about what I did. However, she watches porn 24/7, sexts with guys, takes pictures of herseld naked and send them to guys. I told her that but she told me at least she hasn't been touched or something. She does so many "unholy" things. Lust is one of the deadly sins in her religion, yet she has it and tells me it's not as bad as doing the intercourse. 🤷🏻‍♀️ any opinions or thoughts?
