1stly, you're N0T scum. Don't let ANYBODY make you believe otherwise. Respect is vital, you're right. People that intentionally disrespect you don't deserve your time. People that continuously disrespect you and then blame you when you're upset over being disrespected, uhm, I can't describe them on PC. He's N0T clueless, what he's done is show you he has no interest in showing you respect, and he'll probably find various ways of disrespecting you. i.e. He's not respecting your boundaries!! And he will continue to disrespect you for as long as you ALLOW it. You have to figure out how to show him you mean business. Love is N0T enough, it never is. By that I mean that just bcoz there's love, doesn't mean it's meant to be... I learned that the hard way btw, so I'm not sucking it from my thumb or quoting Dr Seuss.

You deserve better, you're worth way more than you're getting.
