Need Advice

Okay, most of you know I work with my xn (exhausting!). But have done very well with limited/no contact.

There is a work event (that I'm in charge of putting it together) that requires tickets. On the sign up sheet I see that he has requested enough tickets for "the new supply" and both their kids.

Part of me wants to go and not let him push me out of an event that I have worked hard at planning, but the other part of me thinks it will spin me out having to watch their "show" and is probably not worth the damage it may cause my recovery.

I would have lots of support at the event.

Just sometimes feels like he's always winning.

any thoughts or advice would be appreciated.
