Big brother disagrees

Well by the sounds of it your brother really doesn't like him. personally, I would suggest talking it out with your crush, and be reasonable. Tell him that you are really close to your brother and that you don't mean any disrespect, but your brother doesn't want you with this guy. Now I know that sounds mean,and it may be, but, look at it this way, your bond with your brother could end up shattering if you date this guy, or you could hurt the guy you like. in the long run, which are you going to feel better about? I'm not saying that it will happen, its just one scenario. If you do something like that, at least tell the guy your sorry, and you would still like to hang out if he would. (believe me I know it sounds crazy, this guy may end up respecting you more for you respecting your brothers wishes.)

What you should do is try and talk to your brother about this!!! Hes probably doing that to protect you and that's a good thing but certain things he has to let go and realize that your only young once and you need to enjoy life and starting now!! Ask him why he does that? But from there on you should say yes to this guy that is about to ask you out!! if you really like him and he really likes you then you should go out with him and see what happens from then on!! but I would suggest you try and talk to your brother about it!!
