waiting for somebody for a few years?!

I have done that, I think I am still doing it, even though knowing he is not totally open and honest to me with his divorce process. I have been trying to totally forget about him based on the times he has made me down and broken my heart. I just don't understand why it is so hard to get myself out of this situation, especially my Heart! i read item 8 for a few times, hoping get some help and support for me to walk away without look back.....
