Thoughts?

Hey guys. So, here's the question.

So, you can tell from my description thing that Im married with one kid already here and one on the way. Well, I have a small thing with my husband.

He's the sweetest guy in the world, always goes out of his way for me and treats me like royalty.

Heres my issue. I'm scheduled for a csection Friday April 19th. The following Friday is a convention that basically all his friends come from around the world to go to. Its three days. He's said he understands that he can't go but he's brought it up SO many times "jokingly" that I know he hopes I'll say "ok, just go." I usually do not mind him doing things without me. He's gone out of state multiple times for tournaments like this (he plays a card game) BUT I'm gonna be not only 7 days post having his first biological baby but post MAJOR surgery. His mom may or may not still be in town to help us out. I remember for about two weeks I could barely walk after my cesection. I WOULD just tell him to go for a few hours one day and have fun, catch up but the snag with that is he won't. These guys come to play in a nationals tournament, so he would absolutely insist on entering. Which means if he does well (like he usually does) he would have to go for 12 hours all 3 days. I just find that to be way too much time to leave us that soon and I want to make sure that it seems fair. I've already told him they're welcome to come over or hes welcome to go to dinner with them like they always do after the convention closes for the night but he said they will be too busy. Am I being fair?
