speaking as someone who has cut people out of their life
it’s not an easy thing to do, and people don’t generally do that sort of thing without a good reason.
nobody is entitled to be a part of someone else’s life. Find anyone who expresses a sense of entitlement like that to be highly suspect, because this is evidence that they may not have very good boundaries and may be in denial about the effects of their behavior.
I just deleted a long post but I think I will just bold the above, and let the phrase “I knew you’d be upset” hang in the air a bit.
