We can love someone deeply and still grow apart. Marriage as lasting forever is an outdated concept.
If she is really holding you back to the point where you really can't be yourself, it might be better for both of you to part.
Sex and spirituality can be the core of one's being. Who wants to live their entire life with their core needs unmet?
Love withers under constraint; its very essence is liberty. It is compatible neither with envy, jealousy or fear. It is there most pure, perfect and unlimited when its votaries live in confidence, equality and unreserve. -- Shelley
