Truth is itina, he's not thinking. He DOESN'T want to believe it will or is effecting them. He would have trouble justifying what he is doing, if he admitted that it might effect the boys. Besides, if there is OW, undoubtedly she has told him that the boys will get used to it... EVENTUALLY... everybody will be happy, blah blah blah... and who knows more about ANYTHING then other woman.
In my case OW should have known, she is now in her 4th. marriage... hehehe. I assume her girls don't even notice anymore. This most recent h is a year older then our youngest son... 26... and her youngest daughter is only a couple years older then my son. I forgot to mention she is only one year younger then me which makes her 59, or at least as far as we know... h says he looked at her records and she is older then told him... so who knows?
Can we say bat$hit crazy? It will all work out. If you are strong your sons will mirror you, in time.
