It is only when you can honor and love yourself first, that the relationship can be a truly loving one and not one based on need, dependency, fear, or insecurities. When each partner comes to the relationship whole, the relationship becomes an enhancement of your life and not life itself. Most of you have flown on an airplane. There's a practical reason they instruct you to do this. Think about it.
Love is similar to that air mask.
Strap that air mask on good and tight, and you can love an endless amount. If you don't love yourself first, you have no love to give. If you truly put yourself first in love, nurture yourself, honor what you want, and make YOUR happiness the number one priority, you are better equipped to love others. We love others to the degree we love ourselves. Consequently, we love to the degree we're happy.
