...who is/ was a friend of DD's.
She says that she wouldn't sleep with him, and I believe her. But I'm trying to explain that the fact he had sex with the 13 year old (who he knew liked him a lot, but he didn't feel the same way about her) doesn't make him a very nice person.
She says it's the girl's fault for being "easy" - which is an opinion that disappoints me.
What can I say? Or, do I just back off and wait to pick up the pieces?
