I understand the paradigm you find yourself in. I think most of us probably think we would react a certain way in certain situations...but when faced with reality we find, it's not so simple.
I want to say something to you though.....when those women ask you how you can take your H back, ask them if they've ever been in your shoes. Stop worrying about what other people will think or how they will perceive you....cut yourself some slack too. You have absolute power now to drop your previous perception of women who do take their H's back...you now know your assumed perception of these women was off-base. You respect yourself, you value yourself....but you value your M too, you value your H...and that's why people take each other back, not to mention they love each other much of the time.
So YOU are the one not letting yourself respect who you are for taking your H back because you are holding onto a misperception of who you thought those women were whose shoes you are now filling. You now hold the key to letting that go.....so do it.
Here's a thought....when you start thinking those negative thoughts, conciously think of a positive one too. You are going to have to start literally training your brain to do this....it's a very concious thing to learn right now. It's something my H has been having to train himself to do....and I can see a BIG difference.
Hang in there....give this TIME. You and your H have both been through emotional hell over the last several months, it's going to take time to regain trust and your EC, don't let the speedbumps throw you off course.
