<human>: Can you succinctly summarize the text in 1-3 sentences?

My friend has already told two of my friends, while drunk, that he is gay and those friends have told me that he is gay. In the next couple of days he is going to tell me that he is gay and I want my reaction to supportive. I know how hard it has been for him in the past (we've expected that he is gay for a long time) so I imagine that this conversation will be tough for him. I have imagined how the conversation will play out and my honest reaction is to tell him that I don't care that he's gay. It doesn't matter to me. But when I think about I find this reaction to be a little cold. I want to be more supportive and make him understand that it's in no way a problem.

So, dear redditors, if you were telling your friend that you are gay how would you want him to react?
<bot>: My friend will tell me he is gay. How should I react to show him I'm supportive and happy for him?
