Ok, any help on this would be highly appreciated. I have no idea what to do.

This is the situation: my parents have been married for 35 years. Over the years (over about 10 years) I have found several things indicating my father is gay. I am now almost certain he is gay. I have dealt with this on my own for a long time. Last week my 15 year old brother came over to my house stating he had found something and said he thinks dad is gay. I told him I already thought that, etc, etc. We are unsure if our mother knows. I am older, and have been able to deal with this as I never really had a good relationship with my father (maybe this is because i'm a girl...).

I am afraid my brother is not dealing with this well at all, he is now drinking heavily at least once a week...And he's only 15!!!

I have no idea what to do about this. It would break my mothers heart if she knew, and my brother is steadily going downhill after finding this out. I'm not sure what psychological effect this has on a 15 year old boy. And might I add, he's a very "masculine" boy.

Please, please, please help!!!
