Do you plan to find a new relationship after you break up with your wife? Is the desire to come out because of that or because you just want to stop lying to them and be honest about who you are? I will just say that if you have a good relationship with your wife and child, perhaps it’s worth it keeping things to yourself until your son is out of the house. If you leave them, you might find yourself in terrible relationships for a long time, or you may strike luck. But as someone who never managed to have a good relationship and family I wish I had a wife who actually wants sex and children and if I had that I would never leave even if I had to sacrifice a lot. But I do want that, maybe you never really did!?
