They're going to Legoland with their dad. I already said I wasn't going but then we went to a small latino festival "together" (me grudgingly but it sounded fun and I knew my daughter would be miserable and her dad wouldn't deal well with it) and now suddenly they're expecting to do everything en famille. I met a guy at the festival who was a friend of a friend of my ex (irony!) and I really want to go and visit him in Paris where he lives, just to have a nice fling (4 years since we split up, no one since then). Before I met him I had planned to go to London to visit friends while they were at Legoland, but I've seriously considered changing my plans as this is the only weekend I'll have free to see this guy, and dammit, if you can't go to Paris on a dirty weekend once in a while, what is the point in being single?!
So the real dilemma is not whether to go (although feel free to comment on that), but whether to tell my dd14 that I'm going.
Cons of telling her: She'll really freak out that there's another guy on the scene, specially since she wants to do everything as a family and I'll be effectively abandoning the family and going off with someone else (I know, it's all messed up, I can't stand spending time with my ex and would much rather they went with him alone), she'll also be really angry that I'm going to Paris without her! She doesn't really understand that I need a separate life from hers, and is bound to be angry for some reason or other. It will basically rip the rug from under her feet when she's already anxious about GCSEs etc. Also, I don't expect this thing to last long, and quite frankly I want it for myself with no one else offering their opinion of it.
Pros of telling her: there are loads of ways she could realise I was lying (I'm not very good at it, phone ring tones, photos), and if she did she would really find it hard to trust my word. And I would feel better that she knew where I was while I was away, because if anything happened to me, it would be catastrophic. But it could really ruin the weekend for me if I know she's upset, and she might end up telling her dad.
I'm going by plane - weirdly it wouldn't feel as bad if I was going by Eurostar, but it's more expensive and would take much longer.
So I'm putting it out there. What should I do?
