Well did you pay for your ticket into the lucky door prize? If she paid for it I would share one et of the tickets and if you paid it its your prize and yesw I think it is rude to presume you would share them. If you were my friend i might suggested we go out to se it with the girls but I would expect you to use your free ticket and the rest to pay!

Maybe just add on there something like can't believe I have only been to the movies once since high school and dh and I have only been out by ourselves 3 times in x years and one of those times was driving to the hospital when I was in labour! So excited to have won free movie tickets so we can finally go out together!!

that way you are showing her the situation and then after that if she still thinks you should use your tickets on her thats just selfish
