howd you know if you like/love the person and not just their potential?

You fantasize about what they could be and not what they currently are. And even when you break up you are sad over what may have happened had the person actually been THAT person

You can never be totally sure, just have to go with the flow I’m afraid!

I don't think I do...

You you like everything about them regardless how much money they got or if they have a job or not
