Basically friend added boyfriend on Facebook. Keep seeing them online together. Spoke to said friend about it she said she wouldn’t do that, isn’t interested in him just added him because I know him. Spoke to my boyfriend, he thought it was odd she added him. Spoke to my other friend who is best friends with said friend she said she would absolutely not do that. 

But I can’t get the thought out my head and it’s making me irrational angry. I’m going to end up texting her any second and asking.
