Wow.. I am addicted to passionate people. This one is tough. Just because someone loves you doesn't force you to in turn love them right back. I have learned (the hard way) to put my agenda first and if this relationship was compromising me then I would have to totally walk away from it. We can only be truly responsible for our own actions and must not always feel obligated to save people. Sometimes in trying to save someone we lose and destroy ourselves. I noticed in the question you did not mention loving the other person so that means you have the right priorities which is loving yourself first.

Ask me anything
