I'm going to surprise my ex-girlfriend with an overseas holiday with my family. Think that'll work?
Why would you invite your ex?
I thought the trip could salvage our relationship.
You shouldn't invite your ex, you should distance yourself from your ex. Bringing an ex back into the picture could cause a lot of drama.
I don't care anymore, she can come on the holiday and meet my family.
She's your ex-girlfriend for a reason, so I'd leave her out of the picture if I were you.
