My girl bestie's boyfriend is a prick

Not a lot typed up because 1. This is still my girl bsf's bf and I respect her enough not to talk a lot shit about him despite how I feel and 2. I have to beat around the bush bc this isn't rlly my business- but I need to get this off my chest

He acts like he doesn't like her, he gives her attitude for EVERYTHING. She posts text on her close friends and like.. Every time I see something she is TRYING. She is making the effort to talk and communicate to this boy, and she's gotta tug and pull at him to get him to do the same. Of course in a relationship you shouldn't force anyone to do anything but this is shit you GOTTA know how to do when it comes to dating someone.

Again very vague bc its not my situation to talk abt to begin with and I respect my bestie so I wont talk complete boo boo butt about her bf
