would it be okay to pop by his party?

No. It's rude to show up at a party uninvited. It's not the best way to endear yourself to him. Find a way to get an invitation.

hey sweetie. boys are amazing creatures. they love when we do stupid things. my boyfriend likes to laugh at me when i do silly things but then we might be cuddling and he will tell me he thought i was so cute when i blah blah blah. If you truly believe that he likes you too then totally go for it. But be rational. If he honestly did NOT invite you then i wouldn't go, but that's just me. follow your gut. sometime spontaneity is what boys are attracted to the most. however, if you do go act like yourself and maybe you'll score a kiss during the finale ;-)

no dont go .. you wrent invited

I wouldn't show up uninvited, but you should find a way to get an invite. Good luck

If I'm in ur possition I will go to the party and talk to him and tell him about the way I feel towards him...
