Everything changes, everything evolves: people, beliefs, ideals, thoughts, life itself.
Because of blindness, unconsciousness, having idealized someone or something, you sometimes settle for an illusion of love, for relationships that fail to give you the presence and care you desire. You were created for a beautiful and incredible love, so don’t sell yourself short and wait for the one who will love you with 100% of himself.
Learn to change what you want and you will get what you desire. Be a cause in your life. If you recognize that you are the only one giving love, then this is a sign that your investment (energy and time) is not being honored, nor reciprocated and therefore could be given to someone who will appreciate it.
