I have a dad who used to be very controlling (even after I grew up and moved out) but we have a better relationship now. Since my childhood was pretty shit I value having this better relationship.
But lately he has started to send so many random messages about nothing important on social media, and if I don't answer then he will send it again and send messages on another platform and/or text messages. He also "likes" my replies to other people (aibu to find that creepy?) and has followed younger female aquintances of mine who he doesn't know. I did block him on one site, told him off for sending many messages in a row, and won't respond to random memes. This hasn't deterred him. How do I set good social media boundaries with him?
