initially after the BD, i scampered like everyone else, and i was convinced i had lost the greatest woman ever to walk the earth. and i was in immense pain with this knowledge. and i had to get her back, even if it meant degrading myself and giving up any shred of self respect i had, because she was The One, i had to have her back.
but now, after i look back at myself, all of this was simply because of: wanting what i couldnt have.
that was it.
it was not because of her, she cheated, she lied, she disrespected me and my family, etc.
but i wanted her.
only because i couldnt have her.
so, i'd suggest you look at your situation, and ask yourself if this you really want her, or do you want her only because you cant have her.
because i know for me, if i had saved my M, it wouldnt have been too long before i realized what i was going on, and i probably would have made the decision to end it.
