Hi LL,
While "piecing" a M after an affair, those thoughts are common to have bubble up to the surface. But as you continue to rebuild, the days in which those thoughts surface become less and less frequent and the gaps between are filled with more and more good times which in turn makes the thoughts even less significant.

I can't say if they will ever go away all together, as they still creep up every now and again for me, but I can dismiss them as quickly as they pop up as they only serve to remind me on how well we are getting along in the present.
