awww Ellen, I think you sound like a lovely friend. Your mate is lucky to have such a caring and considerate mucca.
As for your friend, he needs to become comfortable with himself, and by doing this his confidence will grow. How long as he openly realised/spoken about his sexuality? If he's only just come out, he will prob just want a bf to prove to people that 'yes he really is gay'. If this is the case, he needs to take time to know what he really wants and to know himself better. You can not do this for him, however I am sure you will give him your full support.
Only when the time feels right and he is ready will be be confident and ready to embark on a new relationship. Good luck to both you and your friend.
