Truly loving people are uncommon. They are as uncommon as awake people. Our success in learning about love will directly correlate to our level of happiness. It is certainly worth persevering with the learning process which involves a great deal of honesty, introspection, and forgiveness.
Even if we are the only one in the relationship on that path, it doesn’t matter. We will still be blessed with our own happiness and isn’t that the bottom line of what we all want? Our first responsibility is to create a happy life for ourselves. If the other person in the relationship learns to also value love, honesty, and forgiveness then the relationship will transform, usually slowly, into a strong connection which is good for the couple and others alike.
