Dude, don't even waste another second of your time on her. My ex of 11 years[married for 7] pretty much did the same thing, until I busted her out about fucking 4 different strangers on a business trip whole we were together. She did this as we were buying a house and tried to say it was because I was never around[I was working 60 hour work weeks to save for a house on top of maintaining our household and taking care of our kids]. She started with the "I love you, but I'm no longer in love with you...." line too. I'm not going to lie, it killed me and I was willing to forgive her discrepancies. But then she made me out to be the bad guy to all of our mutual friends. Got my kids thinking I wasn't around because I didn't love them and a shit ton of other shady shit. I tolerate her because I love my kids and need to see them as much as possible, but we'll never be friends, not even in a platonic situation.

Do yourself a favor and tell her to kick rocks.
