Should I be weirded out my cat is actually showing affection towards me?

I'd be worried, she's obviously been too affectionate with one of your neighbours it's her guilty conscience

She's probably cold. Cats will go anywhere where it's warm.

When my cat does that, he usually needs me to refill his bowl.

Cat on the outside. Dog on the inside. =)

she either wants food or a male cat

Cats cannot be trusted

Uh oh 👀

Maybe she’s getting used to you.
