She's probably reacting out of spite. It definitely sounds like she's still angry about what happened when you were "unavailable".

Sounds like she's afraid you will ditch her at a moments notice. Not sure how to combat that. I would stop saying "I was honest with them.. etc"

That won't make her feel any better. It validates that you did have other women in the wings.

She even says she still loves you but "fear and hurt" prevent her. This other R is definitely a fling IMHO. She's doing it to get back at you.

Sorry I'm not providing much help.
