I'm going to guilt my boyfriend into not attending a party tonight that I cannot attend
Why would you guilt him into doing that?
He will definitely go out tonight. It's not like I don't want to hang out, but can't.
You shouldn't want your boyfriend to feel guilty and stay home just because you cannot go out. Instead, you should encourage your boyfriend to enjoy his time so that he doesn't become resentful of you. Ask him to bring you back something after the party, this will show you that he still thought about you even though you two were not together.
I will throw a tantrum if he goes out.
Don't you realize that he is going to resent you for doing that?
