Why doesn't she trust me with her boyfriend?

I've been best friends with this girl for over 2 years.

Well last year, she got a boyfriend. I became close friends with him too, and now he is like a brother to me. They've been together over a year now, but recently my friend becomes very possessive of him around me. All three of us will be cuddling and she will push me away and say "mine." And other stuff like that. I don't understand, because she is my best friend and he is like my brother, so I would NEVER ever do anything with him.

Why doesn't she seem to trust me with him? Is it because I text him a lot (she doesn't have texting and they are almost always together, so I text him when I want to reach her)? Is it because he's my favorite person to talk to about things? Because I like hugging him and playing with his hair (you must understand, our group of friends does this all the time, is is not even a flirtatious thing anymore)? I just need different opinions and also if I should bring it up with her. Thanks!
