My ex's new girlfriend is really really annoying me.
She has systematically gone through his old Facebook photos of when we were married and liked all of the ones where he's on his own. Most of his photos have our children in (and me as well), so she's really taken her time to do this.
This has actually really angered me.
She didn't know him then.
He wasn't with her then. He was with me (and was for a very long time until he cheated).
She's clearly done this to make some kind of point.
