I agree with QT and CW on this one!
After my 11 yrs break up and the last ex, I had to go to therapy both times. My therapist said "death is easier than divorce because you can closure quickly. With a divorce, the person is still around and you often wonder what they are doing and who they are with"
I know I will get slack of this, but men have a hard time being alone. They need to be taken care of. My Dad's friend was married to the love of his life for 45 yrs, she passed and he had a new women in his house washing his clothes in less than 3 months. He's still with her
This is all about not being able to process pain and the feelings of loss are SO hard and uncomfortable, so it's just easier to meet someone else and live in denial and keep so busy, you don't have time to hurt.
Traz, it's great you're feeling some happiness with this new girl, but you still love your wife, period!
