My brother seems to be too good to be true!?

There really are truly guys out there that are great all around! YOu said he's your step brother, and his child hood wasnt so great! Maybe you are picking up something. maybe he's just protecting you, in fear he will loose you! maybe he needs a little help! Happiness is great, but is he too happy, maybe trying to cover up hurt of some sort. there could be many reason for the way he is, or he really just might be one of the few good guys. Maybe you should try talking to him about all this! Good Luck
