Would it be weird to pay my ex-girlfriend to cook for me?
Why not ask someone else who might do it for free?
I don't trust any other women in cooking.
I think the better approach might just be to learn to cook for yourself, instead of relying on someone else to do it for you. That way, you save money and learn a new skill!
I do not have clue on how to make something decent.
Well, you're in luck! There are YouTube videos and websites that teach basic cooking skills, and you'll get the satisfaction of eating something you made yourself.
