Is your son in counseling? Ox, I have to be honest, I feel for you but there is a lot of dysfunction in your household. Your son needs to be supported, and right now you and your W have trouble doing that because you seem very focused on yourselves and your own drama.
He may have just said that to see how you would react/get some attention. Or maybe that is his way of opening up to you. And if he's gay? So what? How would the NEW, IMPROVED, NOT-CONTROLLING Ox respond?
Think on that one a lot. Do some reading. Your son needs you. This is a wonderful opportunity to take a step forward and step up like a mature, responsible, caring dad.
NO NO NO NO....YOU ARE OVER THINKING WHAT HE SAID. HE'S NOT TALKING ABOUT HIMSELF...HE WAS MOCKING HIS MOTHER, SHE WAS DRIVING THE CAR HE WAS SITTING NEXT TO HER ( oh I'm not yelling I'm laughing)
The thing is my son has had lots of counseling. He had a lot of anxiety issues starting at 9 years old. He is pretty much cured. Likely going to an IVY league or Tier -1 university.
His issues were the straw that broke the camels back in our marriage. My WW could not handle all the stress anymore, this OM promised to take her away from it all..
As an aside if either of my sons were gay it would have no effect on my relationship with them.
