Lmao help

So I'm pretty sure my Best friend is logging Into my Snapchat and unadding the guy she likes and blocking him from my account I know this cause several times today I've been logged out of my account and when I logged back in this last time I thought I would check for him he wasn't in my friends list so I searched his snap name and i had to unblock him and add him again my best friend is the only person who has my password and email I've just changed my password and I find this humorous because we just had a discussion about me having him as a friend she said "your the person I trust the most" and then she goes and pulls this shady shit help I dont know what to do
