This was a very long, but interesting article. Hub tells me often that I show him the most love when I am angry with him, because even in my anger, I still care for him. To him, not ignoring or leaving him just because I am angry, is a way I show him love. To me, his loving me enough to get angry with me is enough. It sounds silly, I know, and this is only one example of ways we show each other love.
What I have noticed in many couples is that each one is as unique as the individuals in the relationship. What I see as love and what others see as "showing one love" are often two completely different things. Each couple has to communicate, be vulnerable with each other and be intimately aware of each others' needs to succeed. Kindness and generosity are great ways to learn these needs about the other.
Great post! Peace!!
