I agree it is much harder from a point of low self worth to maintain a relationship. Loving yourself is a building block to being confident to be open and honest with the one you happen to be with. Short of that, there always be a sense of holding back something which can be harmful in any long term relationship

I still struggle with this one myself, my wife has the patience of Job but I still often dislike myself and rarely ever feel worthy of her or anyone else's love.
