My big brother is always saying he knows what he wants and then talking crap about him should I get mad at him or not
Most Helpful Guy
He's just being protective which is what big brothers do. I don't think you need to ask GAG if you should get mad at him. Your reaction is your own choice.
He's worried that your boyfriend is going to try to take advantage of you for sex, that he'll cheat on/break up with you when he doesn't get any, or otherwise hurt you. Honestly, he is within reason to react this way, especially if this guy is your first boyfriend (I'm assuming he is). That does not, by any means, mean that your boyfriend is going to be what your brother worries he may turn out to be, but at this point in life, there is a distinct possibility.1
