We are here to awaken from the illusion of our separateness. - Thich Nhat Hanh
Feeling chronically undervalued in your primary relationship is a subtle kind of misery that eats at the soul. It can be a withering process of uncertainty and self-doubt that can build to self-loathing if we don't take action to counter it. You are at the core of all you experience. Take action. Make choices that lead you in the right direction according to your own needs and values. You are the only one who can make sure you get all you deserve from your partner. Talk. Negotiate. Decide. Do.
Get out there and Live Richly.
