I remember when I first heard this quote, which was a lot different than when I heard it in proper context years later. Essentially what I've broken it down to is as follows:

"If you can't handle me at (something really bad), then you don't deserve me at (something not really bad)."

This is problematic I've found, because people often have very blinded perspectives on what constitutes "bad" versus "good/not bad".

I find it binds itself into becoming a sort of excuse for bad behaviours in relationships. Now I'm not saying that this is wrong because it recognizes our own human weaknesses, but I'm saying it's wrong because it seems to be acceptance of negative behaviours rather than imploring self-improvement. I personally see nothing wrong with being human, but I see something wrong with accepting your own bad behaviours and refusing to deal with them in a constructive, positive manner.

Anyways, I was just thinking about this sort of thing in relation to my own relationship experiences and was wondering what others might think about the topic.
