25--my H was mildly selfish and sometimes lazy without a lot of ambition. Seven or so years again that stuff began to ramp up. Now he is insufferable. Naricissism becomes worse in stress and times of crisis.
I too am in the same place of just wishing that I could resolve the financial end and have some finality. I don't think he'll let me unless another woman stays around long enough to force him to do it (but even then he hates being told what to do). Mine never mentions any of the women on FB. Just creepy love poems and the like. Shots of places he must be talking with them about visiting. I think that's because he knows none will work out and he doesn't want to look like a flake.
Leahsue's story is why I have not and will never file D from this man. When he wants it, he'll file for it.
Sadly I think yours is going to fight you to the bitter end. Unless he really wants to marry this woman. Maybe that will cause him to see if through. If so, that is nothing but good for you at this point. I guess my point is to let go of who he has been for the last 35 years and see him for who he is now. He doesn't have your back and will do horrible things to hurt you.
I agree affairs aren't the worst. In my case it is the hot and cold with the kids and the way he royally screws with their emotions. I fear that mine will struggle as Leahsue's have.
