"Does it sting any less after a while?"

I'm gonna sound like a barrell of laughs, but no. How can that not hurt? I think it would hurt me.

I am constantly suprised by people and relationships. Something will happen in either one or both of your lives that will make you want contact again. My only suggestion is to be open and receptive when she makes her move. In the mean time, if it were me, I would work my tail off trying to forgive her. She may be hurt, but she is in this with you. Does that make any sense? (my brain-fog, fog, fog.)

I am trying to say that it takes two to fight and you didn't do this all by yourself. You sound like you have allready made peace with your side of things. She must still need time to sort out her end.

You could send her a congrats card in regard to the wedding. Just to let her know you think about her. Maybe?
