They've been doing it for years. DP said in some ways he does want to go as he wants to spend time with his kids plus friends and their kids all together. His DC are 10 & 13 - they've always done it every year pretty much.
Last time him and exw were on the midst of divorce and he shared a room with one of his male friends and she shared with his wife (think country cabin type thing). During the days he was in the pools etc with the kids and his mates and in the evenings he'd play cards/games consoles etc
All the couples have booked for next Easter and his exw has asked if he wants to come along too.
He's asked me what I think/feel. I know he wants to go as he's always had a good time as have his kids but I can't stop thinking they'll both have a good time and want to try again.
I've no substance for this feeling but I can't help it. I've said it's ok if he wants to go though
