Let go of what you think someone wants you to be and free yourself. Let go of what you expect someone else to be and free them. Let go of what you think your relationship should be and free you both. If the relationship remains or fall apart it will be because it was meant to be. ~ from my own experience.
Love is the most challenging and rewarding learning experience available to us, in my opinion, because it challenges us to find love and respect for others while loving and respecting ourselves. Happiness doesn't come from outward projections, it comes from how we perceive and interpret our experiences and how we translate that into the emotion we will associate with our memory of the experience overall. Again, let go and life will flow.
