Are saying that I should give up? Or that you are not aware of anyone on the site who has had an EA/PA that has been able to reconcile?
What did your wife do when you were cheating on her? How did she get you back? Did she get you back by being afraid that you were leaving, by crying, begging, pleading, etc.?
Probably not.
I think you need some time on your own to grow up & mature which is impressive, I think it's assumed that when a person reaches your age that you would already be grown up & mature.
