For what it worth, and I'm no expert, I think your h is still trying to get a reaction out of you, and not necessarily in a bad way, if he was truly 'done' ( and boy doesn't that sting!) why would he care how you felt or if you were still mad? I think you handled it beautifully, you were light, breezy and non committal, especially liked the bit about being sleepy so you didn't have to give an answer!
I think keep doing what your doing, use the forum, I completely understand, everyone in my life thinks I'm crazy to want to start m to my h, everyone is saying he's an a#hole buy I still see glimmers of h, underneath it all.
I think you will know where your line in the sand is, I keep getting asked that and I say honestly that I don't know yet but I will know when it's time.
Keep smiling lisa, you've got this smile
