Rachel, writing it out is absolutely the way to go. DO try to release all the upset as much as possible by writing, writing, writing, walks in nature or whatever. You are depleting your inner Light and Energy, hating - and, believe me, I'm not preaching. Simply sharing what I have learned the hard way. Karma WILL get him. Allow Karma to work WITH you. Put out light, light, light as much as you can so it comes back to you.
