I really appreciate your insight. You are correct, there was definitely conflict in the relationship and things ended quite badly. We have not spoken since I moved out seven months ago. I have had a difficult time with the breakup as we were best friends and did everything together. What is most shocking is that he seems to hate me and has threatened legal action against me (he has sent a couple of emails and left one phone message).
I believe he is the one that has moved on while I am still struggling.
