He's a grown man. He's gonna do what he's gonna do. He's not your little boy anymore, hasn't been for a while.

Grit your teeth and mind your own business. He's old enough to deal with the consequences of his choices.

I was married to one. For 29 years I forgave and hoped she had learned and things would get better. And she resented me asking her to do the right thing so much,she turned to alcohol. I stress ate, did not know what she was doing, just sure she resented me and did not want me any more. Kind of heavy sentiment here, but that was a lot of my prime years lost to wishing she would be someone she is never going to be. Ask him if he would rather be shopping for love at 50 or where he is. Life is too short to spend it wishing others to be more than they want to be.

Do absolutley nothing !! Whatever happens he must find out himself . If you do or say anything you will be blamed fro everything and it will just make you the bad guy . Just be there for him no matter what he decides to do . She won't be there forever you will

He's going to have to find out for himself.

His hormones are directing his thinking,how old is his love interest? So,he's 34 probably want's kids,and finds her,she might be looking for a meal ticket.Have you met her? Don't be Judgeamental until after a meeting.
