Stop questioning something really great that has bloomed in your life, dear Moonchild. That will only make you insecure, and it will also put a strain on someone else who is involved in this. Someone has made a promise to you, and they intend to keep it. Try to accept this as the whole truth, and don't allow doubtful thoughts to creep into your mind. Enjoy the experience. Rely on it. You are someone who keeps your promises, and you have to trust someone else who makes a promise to you.
