This seems like a good idea. Just kidding.

Seriously, IMHO, if you want to go, go. if you don't, don't. But only go if you intend to enjoy the party and you already know people there, other than your h. I recently went to a business dinner with my H, not knowing anyone. But we are piecing and I am going as HIS (corporate) WIFE. So that's OK. Since according to him, you two are getting a D, then what role will you be at the party? Not as a wife, not as a partner (cause that would be OW), ??? But if you want to go to see friends and enjoy yourself, i feel that's OK. I don't go as a trophy (stbx) wife. These H is funny, the thoughts are all over the place and totlaly illogical.
