it means taking a step back. Getting out of any relationship and doing things for yourself. Taking up a hobbie/interest, going to the gym and boosting natural endorphines, masterbating without any men, getting to know your own body, travelling, meeting new people (not men) etc. etc. Once she is content with herself, she'll have a better understanding of what she wants in life and ultimately what type of man she pictures herself with. And hopefully with enough love for herself, she won't do stupid things like settle with someone she doesn't love. Simple enough?
