It's taken me almost 2 1/2 years to get to where I am now, simply because I didn't stay the course in giving complete forgiveness to both OW and my H and I didn't properly DB. Trust me, I've gone through some pretty irrational, immature times with both of them. But again, I know all that does is further damage my own M and just makes the OW satisfied. She isn't worth mentioning, and the incident isn't worth mentioning. My H and I have come way too far in the past 2 weeks for her to go blowing it just because she apparently didn't take her happy pills yesterday and threw a little fit with her grocery cart.
For the past 3 years, I have lived the perfect example of what NOT to do when DB'ing. I'm trying to turn that around, before it's too late. You are equipped with all the right tools through the MWD books and this website to make better decisions than I did. I have great hope for you and for your marriage. Stay the course!
