I still lurk here, even though I'm divorced now and totally over my ex. I do find it helps keep me focused in a good way when it comes to my dating relationships.
What stands out to me here, is that it doesn't sound like your partner tried to go to counseling with you to save the relationship? Yes, I know - typical WAS behavior. But really, wouldn't any of US, here, if we became unhappy in our relationship, try to fix it first by going to counseling? Do you think the women you pick somehow are flawed in that respect? Looking back, are there red flags that you ignored? (I am famous for blowing right past obvious red flags in my relationships - I still do it, but I am TRYING to learn to look for the signs - and to figure out what it says about ME, that I am attracted to the types of men I am).
