Yeah, we can each admit to treating our S horribly at times. But just like we chose how we treated them, they chose how they would respond. They could have SEEN the problem, sought help, reacted differently, but did not.
We can each see the past and say shoulda, coulda, woulda. Unfortunately we can't relive the past. We can only work with what we have now and pray our spouses accept the new us.
Keep going forward with the NEW you and let the past go.
