You don't have to show them the receipts about every little thing they've done to wrong you, but Dr. Bonior says you do owe them the expectation of what's to come between the two of you by saying something like, "Hey, I'm sure you noticed I can't hang out much, and to be honest, I'm feeling my life pulled in different directions. I'll always value our friendship, but I don't have time to devote to hang out." This works well because it gives them clarity about what they can expect from you moving forward. "If someone meant something to you in the past, you owe it to them to end it in a graceful way," she says.
