Ok, DO NOT PUSH. It sounds like she may be coming around, but don't get too excited and end up pushing her away.
Also, it would not hurt for her to feel some jealousy if she thought you may be dating or seeing someone or at least getting yourself out there.
Obviously, OM isn't the gem she thought he was. Don't push to find out what happened to make her be feeling the way she is. It really doesn't matter; you know that he has obviously done/said something and it could be that she's second guessing her decisions. THAT'S all that matters. Just hang in there & go w/ the flow. Be there for her and be the one that is constant.
