Actually Monet, mosques can be used for community purposes as well. I guess even weddings.
chideltjen,
I don't think it says any where in the Koran or other holy book that a muslim man can influence a non-muslim woman into the religion. She can keep her religion (as long as its one of the religion of the books) and not convert. It depends on what sources your teacher used to come to his/her conclusions.
