Communication
As two people grow together they change. Life changes, opinions change, desires change, goals change. Communication is important so that you can understand each other as these changes happen.

Communication is important to understand the feeling of your other half and for them to understand you. I think it important to be on the same page.

Love
Everybody has faults. But if you love someone the focus should not be the faults, but the love of who they are, for better or worse. Personally, I know I can be hard to deal with, I don't always think logically and I can be stubborn as hell. But I am forever grateful that my husband loves me no matter what. And it doesn't matter if he does little things that irritate me. I love him more than anything. After nearly ten years together I don't want anyone but him.
