Coming Out Support Group
This community is dedicated to the challenges that gay men and lesbian women face, both between the partners in a relationship and from other influences (family, society, etc.). Find support and talk to others who may be facing the same challenges, and share your experience.
What did you say to the question? It is possible a straight "yes" may have been the best way. You know your son best to judge!
Your son, I am sure, will eventually come round to the fact that you would not have come out if you were not going to do anything about it. It is possibly still a bit of a shock, in which case giving him some time to adjust may not be a bad idea.
I would continue with your plans and just give him some warning if you are going on a date.
Cheers and good luck with the dating. Get out there!
