Is it normal to be jealous of her boyfriend?
So I'm the girl who never had a big group of friends, and the ones who I do have are basically all guys. Then one day, a new girl came to my school and we hit it off amazingly well. She became my very first great best friend. I can totally be myself around and act as stupid as I want, and she will join in and wont think I'm weird. I've told her things that I've kept to myself for all my life. I'm so happy I found her and that we get along so great.
But then she got a boyfriend. And I want to know if what I'm feeling is normal:
I'm starting to feel a... jealousy? towards her boyfriend. Like he is taking her from me. I mean we still hang out a lot at school and text sometimes but not as much. And she hasn't been that eager to come over anymore. And her boyfriend's friends (some of which are my friends, and i have a crush on one of them, dunno if that's relevant) always crowd around them and it's making me feel like I'm being pushed away.
I'm scared to tell her how I feel because I'm afraid she won't take me seriously, or will be freaked out or something.
So, are my feelings normal? And what should I do?
