My girlfriend has another guy as her #1 bestfriend on snapchat. How do I deal with this?

Anonymous
So we've been #1 bestfriends on snapchat for like 3 months but a week ago the pink hearts disappeared and when I checked her phone there was another guy on 'my spot'. This guy (Let's call him Jake) was the one trying to get my bestfriend's ex by first snapchatting a lot with her and trying to kiss her after in a club. Later my friend spoke to him and he denied everything. Whenever I talk about this pervy Jake my girlfriend just brushes it off and says it's nothing but happily keeps snapchatting him. Should I be worried, because I am. She's no slut though but I think she would unintendedly cheat on me when she'd be drunk. And in what way should I tell her that i find this uncomfortable? Thanks in advance!
