Loving myself is way important then trying to love soneone else. Ive learned from exprience that no matter what if your in a relationship or anything else dont never love that person more then you love yourself.
When you are self-assured, there's no reason to use others to find your self-esteem and worth. Its how I was brought up and live and now impart to my daughters. Depend on yourself and your internal core values and not external things such as validation from others and you will always be confident. I wish you luck.
