Dude my girlfriend's mom still invites her ex husband to Thanksgiving and Christmas. He's never showed, but I had to pull her aside, because it's clearly upsetting my girlfriend. I don't know why parents try to do this, like what planet are you living on?

When I become the ex, I cut all ties. No family, no friends we share, no alone time with them. It just makes things awkward, and causes pain to everyone involved. On top of that, I don't want to see any of them anyway.

Cut ties with him, you'll feel 100% better being free to pursue someone that actually cares about you.
