Is it dumb of me to be upset?

Sydney

Should I be upset that my bfs friend keeps making me feel like I cant do anything? Like he makes it seem like I'm incapable of doing a certain job cuz I'm a girl. Also am I over reacting when I get mad and jealous that my bf adds random girls on fb and always likes their pictures? I've told him how crappy it makes me feel but he continues to do it... Lately I've just felt like I'm nothing and not good enough....
