Mate, I know exactly where you are coming from in regards to the loss of attraction and respect for your W.
I have gone through these emotions as well. And I am scared that I am fighting for the wrong reasons, and maybe I am competing against OM rather than really wanting her back?????
I am scared of my response if W did come back and did break it off with OM.
I just hope is doing things for the right reasons. I can see how her mood and personality has changed over the last few months, and see the turmoil and the resignation of what she has done. Clear as day now (for me), and not as cloudy as before.
Also, the feelings will change for you. I really do care and feel so sorry for my W. I can look back at how things happened and can understand why she did the things she did. I look back at my life with her, and other than this huge mistake, she really didn't do anything wrong.
But in saying the above, I do understand how you are feeling.
Hope you and your family have a great New Year, AndyV
