Your ego has now been fully stroked, you feel good, that's what she wants you to feel, secure.
The fact is until she is willing to shut OM down, your a plan B that's being stroked still. I honestly feel that if she was really done, and had that regret, she would have broke it off BEFORE she came back to you.
I hope i'm wrong, but I see this getting out of hand again soon. As she yoyo's back and forth. I also hope you don't catch anything, you know your wife has been with another man recently right?
