<human>: Can you provide a brief rundown of the text in within 3 sentences?

Since I started dating my gf I knew she has both male and female friends which didn't bother me at first. As we continued to date things started getting more and more weird.

 For starters; almost all of her male friends have feelings for her. I have asked her why she continues to be friends with them when they have made it obvious that they want to get in her pants and she says it doesn't matter cause she just sees them as friends.

Secondly, she has guy friends at her apartment late at night and even has them stay the night on some occasions. I know this cause she uploads snapchats of her and her guy friend in her apartment late at night.

Thirdy, she's waaaaayyy to friendly and is one of those girls who thinks guys see her as just a friend. Some guy at her work invited her to a party and she was gonna go with him but couldn't since I was spending that night with her. I asked her why she would go with this guy to a party and she says "cause he's nice and wants to be friends. 

Is it possible that shes faithful and is literally just friends with all these guys? Most people would dump their gf/bf if they stayed the night with another guy/girl, but the thing is I have no way of telling if she's cheating cause she just says "he's a friend".
<bot>: Gf is too friendly with other guys, and OP has no way to tell if she's cheating on him or if she's actually just friends with these guys.
