Cross bow its quiet and it doesn't run out of bullets it has its draw backs (pun intended) but with practice you could get by and since hordes of zombies wont hear you every time you kill one since the bow is quiet you wont need a rapid fire weapon, you should do melee weapon of choice too, I would pick an axe, perfect for cracking skulls because its so heavy also it could prove useful in other situations that could occur during a zombie attack. I mean I love katana and washitaki type swords but they would get so dull and the lack the weight to easily break through bone so axe works unless you can get your hands on a mace/morning-star, which is unlikely unless you happened to be in a museum or medieval castle during the out break. BTW girl friend not getting it thing, i totally get where you coming from, she doesn't understand why i keep like 5 knives hidden about the apartment at all.........
