I agree with that. If you don't love yourself, you are dependant on your significant other to give you all of the love you need, which means you are always too focused on getting the approval and validation from them. Relationships are a lot more stable when both members are content with themselves, so they can truly focus on loving the other person :)

I didn't love myself during my relationship so much so I kept telling him he deserved better and I always tried to break up with him because I thought I was the worst person on the planet. We broke up (not because of how many times I had asked him to, just because we weren't making each other happy anymore), I started loving myself while moving on, and my attitude has improved a lot.
Me and my ex are in contact now, and I don't feel the same way about myself as I did whenever I was around him.
So yes, loving myself has helped me to love others too.
