To begin with, you reached the "Friend zone" when you became her therapist. She was never "in love" with you, you were support for her issues, not a love interest.
Are you SERIOUS? I wasn't doing anything for "fun" and neither was she. I didn't agree with her reasoning, and she had her own reasons as well. That's not "bashing each others religions"
She probably is mentally ill, or clinically depressed or something of the sort. It seems like she just blatantly used you...might as well move on and keep your chin up.
Personally posting here was a bad idea because it's obvious how much these forums hate religion.
You're naïve and though she really wanted you, you got burned in the end. stuff happens, just don't beat a dead horse. Move on and you'll be fine.
