I drew my line in the sand! It took almost 2 years for me to do this. I begged, pleaded, talked, read and had it pretty much consume my whole life.
I am 47 and was not married to this women. We broke up and I started to date around. After all those rejections, I HAD too to do this! My confidence came back in 3 weeks! Yes, I was amazed.
Funny thing is that now my X-SO is wanting to work things out. The plus is that now she knows it is a dealbreaker for me. We'll see what will happen.
I think I was a little more forcefull than you. I talked about this way too much and had a few outburst but that was early on. I should of drawn my line in the sand after 6 months!!
I did read the No. More Mr. Nice Guy book. My X-SO makes comments that I have swung the other way. Previously, she said I was this type of guy... blah, blah, blah...
