My goodness I just skimmed a few of your other posts, you’ve got to find a way to untangle yourself from your son, he has you spun up tight in his web, like a toy that he can take off of his shelf whenever he wants, he demands that you “play”. I wonder if he would appreciate it if you were the one constantly relentlessly demanding his presence or favors every hour of the day. I see this sort of thing a lot online nowadays, the entitled parents just pushing and pushing the grandparents to “preform”. It’s the inverse of the overbearing mother-in-law schtick! You must be so touched out, I’m sorry.
Is it possible for you to cut down on some communication with him? As in, take an extra couple of hours to response to any of his messages or calls, become a bit unreliable in the sense that he no longer expects a prompt reply when he snaps his fingers. Maybe you’ve gotten a new phone or changed your ringtone, so it’s harder to hear when the phone rings and “no son I won’t change it back” because you got sick of the old ringtone. Or even the battery on your current phone is “shot” and you “have to” keep it plugged in much more often, therefore you aren’t as available because your phone isn’t always in your pocket.
Normally I wouldn’t suggest the above because it’s not the healthiest thing to tell white-lies but I fear that without an alibi I suppose your son would retaliate. Terrible that you have to live this way.
