A healthy marriage is one very long conversation. Expressing your feelings in writing is good for the soul. Your life is not about pleasing everyone else. Live your life daily with a sense of gratitude. Worrying is a total waste of one's energy.
Age is all in the mind.
As we get older, we get better. Always express how you feel honestly, especially when you are having a bad day. Painful and negative feelings are okay, as long as you don't dwell on them. When love ceases in a relationship, familiarity and comfort are what keep many couples together. Familiarity and comfort are the worst reasons to stay together.
