It is easy to attribute your self worth to the person you are dating/married to/ with; we think “so and so loves me so I must be special.” When we have that mindset we end up making all kinds of sacrifices to stay in a relationship that might be more work then play. We will just date anyone because it appears to give us value, meaning, purpose. That is a good indicator that the relationship that needs the most work is the one you have with yourself. You need to stop chasing after mediocre relationships with less then worthy of your love partners and start chasing after your own hearts. You need to win yourself over. Fall in love with yourself first, and trust me, the rest will just fall into place.
