Hey I'm 25 years old I live with a familly that they helped me in my life ,the son he is 30 years old he likes me so much he was telling me you are the nicest guy...
And I'm gay !they don't know about me specially him but when he drinks I feel that he wants me but I'm scared to tell him or to ask him if he likes guys too or not .even in his wedding at the end he was asking where I am make sure to bring me home before anyboddy leave.
Till his wife now she thinks that something between me and him why she thinks I don't know till know there is nothing between me and him I love him I feel that he wants me too but he can't . But many times he was doing things like touches or eyes attractionds
What should I do to tell him and then I'm afraid to lose him or to keep it inside?

If he is married, you do absolutely nothing at all. He is strictly off limits.
