Deal with it?

You know when you meet someone or have an attraction to someone(whether you know them well or not), and it seems like anything and everything about them is cute, funny, fun, clever, smart, perfect, and the list goes on...They seem like someone that is perfect for you in every way, even if you don't really know it or not at the time.  Why is it that there is always a hidden deal breaker.  And it's not like it's something that is always on your mind and you're watching for it.  It's something that randomly shows itself.  

You run into your crush at a bar only to see him wasted, sloppily dancing and ever so sloppily making out w/ whatever is in front of him.  Oy!  I get it, he's single and he's gonna go out and do his thing(whatever/whoever that may be), blah blah blah, but if that's a preview of the future, well, I'd rather jump ship!

Or maybe he's just a BIG partier.  You know, the super late 5am-6am partier w/ the crazy eyes, and a mouth like CHATTY CATHY followed up w/ no GOOD intentions.  Hell who knows, he may not have any intentions at all.

So when this person could be the most physically attractive man w/ an AMAZING personality, and you two have so much in common, well...why is it that a deal breaker always seems to show itself????  Why is it that after seeing a side to someone you don't want to see, well, it totally turns you off.  Every angle, every switch, every everything and anything just gets completely shut off.  Is there anyway to just brush it off and DEAL with it?

Can one DEAL with a DEAL BREAKER?
