it means that some people think they are that worthless that they will settle for abusive love. they attract the people that treat them how they think they deserve to be treated. others may have their sense of self-worth so won’t settle for anything below what they deserve. how you view yourself is how you’re going to be treated is what it’s saying. so, if you think you deserve more for yourself, that’s what you’re going to get, but if you don’t think you’re a good person, you will settle for much less than you really do deserve. don’t depreciate yourself, because one day you’re going to find someone who will give you everything you deserve and more.
