What stands out to me is that XH didn't jump to ow's defense when you were asking him about wanting her hair and your suspicions. Now, once he processes all that you've told him he still may come to her defense, but if he doesn't, well jeez, he may just not be that into her.
You've given XH a lot to think about. Prepare yourself for the possibility that he may retreat for a while to process.
Your exchange with your XH sounds very positve, especially the part where he acted protective of you. You at the least know he cares for you.
Please be vigilant and watch out for yourself. MLCers aren't known for picking the most stable of people to become involved with while in the fog.
Sounds like your XH may be awakening and hopefully realizes that the best one for him has been there all along.
