Is my boyfriend flirting with his male best friend?

Anonymous
I went through my boyfriends phone. I know, I know, its bad. But I was just curious and when I secretly watched him put his password in I just did it. He wasn't texting girls but his text between his best friend is really fishy. They were telling each other stuff like "I miss you" and even using heart emoji's. And at one point during September his best friend said was I home and could he come over and "chill" again๐Ÿ˜‰๐Ÿ˜? Literally wrote in quotations and with the smirking a winking emoji. I dont know whether that is gay or not but is my boyfriend and his best friend sound like they are fooling around or flirting with each other?
