Hello Guy,
Sorry to hear the bad news. But you wondered what your place was in all this, so you ready…
It’s not… you have no place in this, she left, she made her choice, you and her BOTH moved on, it’s over.
Yes we have compassion, but this is hers to deal with. I’m sure her new man will be there to hold her hand again and you need not worry you’ve done the work for yourself, you deserve NOT to be bothered with it now.
Take care of your kids and if they care to see her then let them see their mother, other then that you have no part.
