Ex always comments on FB about my extended family

[KeziaK]

My DB has just put a Christmas greeting photo up on Facebook and my ex has commented on it. We split a decade ago. I feel really uncomfortable about this.
I then looked on the profiles of my cousins, nephews, neices etc and have seen he is often posts although he can have onl met them once or twicw as small children.

Block him.

Your extended family need to sort their privacy settings out!

I cant say this would bother me. He must have them as friends

Just block him then you won't see anything he posts.

But if your extened family are happy to have him as a friend on fb and don;t mind interacting with him then that is all that matters. This is between him and them, and not about you. If you can't stand seeing it then you need to alter your settings and friends list, not expect everyone else to alter thelrs.
