Perhaps this guy is more attracted to you than you are him. He may seem like a big brother to you, but his feelings may be sexual and he's been hiding them from you. Alcohol, being the big inhibitor it is, may have brought out those feelings, not to mention he was drunk too.

If you feel like you can't confront him, then just be cautious and aware of the situation the next time your around him. He probabaly just got a little carried away, but I wasn't there so I may be downplaying this too much. Whatever you decide...caution, caution, caution.

Take good care of yourself,

Missi
