Feyth, I am glad you had fun. I went to a holiday party last night too, with my H, but barely exchanged words with him. It sounds like you had more fun than I did.
I like Vanilla's description of detachment, it is helping me too. I don't have much to add, just want to empathize with you and offer my support. And, for what its worth, you didn't say anything bad about the IL's. No, it wasn't all rainbows and sunshine, but you sound honest and you sound like you care about them, I wouldn't think you were speaking unkindly of them.
