If you think someone is crazy, but you get along with them, and they like you, should you get together?

I mean really understands you, but you don’t understand them. You have no clue about them except for the fact that you know they adore you, are attracted to you, and a positive influence. But the whole thing is not being able to find other people that understand you so well. and being in at a point where your damn sick of being alone. And another thing, you cant predict them for anything. You never know what they are going to do, but its not all bad. Should I wear the pants here?
