If you feel like going out tonight, then you should go. There are going to be other people there who you can socialise with and you can still have a good time without having to make much of a conversation with the host.
Definitely avoid confrontration with him for now because he's the host and such.
He's invited you and so he obviously does consider you a decent friend for him to invite to a small gathering.
I'd go if I were you, but only if you feel like it, don't go if you're not that sure because people don't like to be around other miserable people and you'd make it unfair on the other guests.
I do see where you're coming from but I reckon you should go and just have a good time and enjoy yourself and have a decent night out.
I wouldn't say your being hypocritical myself because it's so difficult sometimes to tell someone how you really feel especially when you find that they're your friend and everything they do starts to annoy you.
Maybe it's just a phrase you're both going through?
