Should I crash his party?

go to the party, but have someone else crash it for you and act like you never meant for it to happen, but if you don't want to do that, thats okay too

That would pretty much be gatecrashing. If he really wanted you to go he would of somehow contacted you so you could go. Only go if your friend told your other friend that you could go

u have the reason why she not invited you as she donnt have your no but as she got your no she invited u na then you can go nd enjoy there

Of course, you should go.

Can tell you like him. Why not go there and have a talk?

At least have a chance.

Yea he didn't invite you cuze he didnt have your number. So your his friend go!!!

only if your positive thats the reason you werent invited. otherwise, it could get awkward.

hell yeah

just if you can tell him before

or bring something

go, wear something sexy and revealing and he won't mind you turning up... ;)
