Do Luke and Lorelia ever end up actually getting married? I've seen every episode on T.V, but I never see if they get married! PLEASE help!!!

No.
Unfortunatley Gilmore Girls ended with a possibility of a siguiente series but Alex (Rory) and Lauren (Lorlei) agreed not to do one...
therefore it ends where Lorlei realises how much she loves Luke and they just kiss.
It's a lovely ending though :)

At the end of the mostrar they are not married and during the last episode Luke eludes to the fact that he will wait until he and Lorelei are both ready to tie the knot! LOL!!
