Yay, first one to congratulate. Be grateful, many a sibling have shown bitterness over little things like this. You have a great brother! Now i got the warm fuzzies, and i wasn't even there!
lol although i am sure that you feel the response is lacking, it is awesome. lol my sister is going to be all like i knew it!! i knew you were gay!! and then never let me live it down siblings are odd
Disappointingly short when I think of all the angst you must have put yourself through before coming out but still a positive reaction. Maybe he just isn't the expansive type. Maybe you feel this isn't a very supportive reaction over something that is so important to you but it is in it's own way. Look on the bright side, it doesn't make any difference to him and thus to your relationship. Is he older or younger than you? An older brother could have tried to be a bit more supportive and understanding of what you had to go through before coming out but if he is younger then you just have to put down his insensitivity to youth! Someone who has not been through all the anxiety of "am I gay?, am I straight?, should I tell?, should I hide?, can I do this?", cannot imagine how hard it must be and I think that is why you got such an nochalant 'who cares' attitude. Who cares... you care and I understand that you might be feeling hurt and let down by his response but don't let it get you down.
^ That's right. It could have been worse. Good for you for being honest and brave enough to tell him!
