Very very poorly lol. I tried to give my mom my coming out letter, but it wound up in a long conversation where I was evasive and eventually came out. My father got the letter (it was not a good letter, I was young and emotional and wrote it in a burst of courage and emotion) and while he wouldn’t’ve likely responded well no matter how I came out, I’ve always wondered a bit if how I did it influenced his decision to stop talking to me. Meanwhile I was going to come out to my sister with a stupid pun so my mom outed me to her.

But yeah, pull him aside and be honest. It’s scary but simple and honest vulnerability is far better than the crap I did. That’s what I did with a friend, who was so supportive that a few years later he thought to respond to it with a statement of acceptance (he’d been nothing but supportive in those years lol)
