Sounds like he is planning ahead and making sure he doesn't make the same stupid mistakes everyone makes in zombie apocalypses. I say you have yourself a keeper

That could either be good or bad. If he would kill you after you were bitten by a zombie, that means he loves you and wants to spare you becoming one of the undead. But if he would kill you if you had NOT been bitten (or injured to the point of being unable keep moving) that means he considers you baggage and a hazard during zombie attacks. Though thats unlikely since slower people are an advantage to you when being pursued by zombies.

My boyfriend also told me the same thing :(

that sounds exactly like something i would say

what are you on about!? this guy obviously cares about you and is thinking about what he would do in an emergency. and the fact that he thought about that particular emergency is adorable. hes a keeper.

Ydi for being able to get infected by a zombie.

That is the most beautiful thing I've ever read (which referenced the zombie apocalypse). He's a keeper.

Was it a "kill you so you don't have to experience this," or "kill you 'cause your a bitch,"

Could be worse, he could have said he would use you as a meat shield.

This is MLIA, not FML. He's just being nice.
