<human>: Sorry for the amount of reading first off.

Okay I've known my girlfriend for 5 years before we started dating, we're best friends, and she's also known B for a little less then she's known me.

So we started dating 3 months ago, and everything is going great, I have so much trust in her, and I also trust B as well, but I still can't help but let it slightly bother me that they sleep in the same bed. 

So she's on her spring break right now, so she came to stay with me monday-thursday, then she had plans to hang out with B on friday, so she left thursday night to go sleep at his place, and friday (which they planned). but after they made their plans, I asked her to come over Saturday to hang out, see a movie, and spend the night.

She seemed frustrated with me, and she said "I want to keep it fair, so I stay at each other's houses the same number of days, which I guess in a way makes sense, but I'm her boyfriend shouldn't what I say mean something? Because she said " well B asked me to stay the night first". Actually I asked after they made their plans for Friday night only.

Plus a little something extra, when she's over at my place, her phone is always charged and her and B text, and she calls him at least 3 times during the day just to talk, even while we watch a movie or TV, but when she's there she says her phone is always dead, and when I do get a call through, she lets me go because they're watching a movie.

So my question is am I wrong for being bothered because it's for 2-3 days?

Give me the gist of the text in a nutshell
<bot>: GF sleeps in the same bed with her guy best friend. always goes out of the way for him when she's over, and when she's there I'm "swept aside".
