Your boyfriend did what you asked of him, and his friend apologized. It also doesn’t sound like there were any rules explained to the friend about not having a guest over the house while he stayed there. This adds up to a misunderstanding and an error. You are welcome to hold a grudge and drive a wedge between yourself and your boyfriend, but I’d consider lightening up, forgiving these infractions and not creating more from what this is.
Wishing you patience and peace,
