If you're not ready to settle down and are perfectly happy just having someone convenient to date, then you don't need this article. Even if you're unaware of it, you may be in a low-level depression.
Unsatisfying relationships are depressing.
Also, you're probably upset with yourself, perhaps in an unacknowledged way, for spending time with someone you know is wrong for you. Sure, you tell yourself that you're only going out with Slimey Sam or Nutsy Nancy until the right person comes along. The problem is that when you're depressed, you're not at your best and most attractive, so you're not attracting the right kind of people. Worse, you may be actively repelling the right kind of people. People hear about other people's reputations.
