There's a really good book which discusses the dynamics involved when a partner abandons a relationship. The author talks about the withdrawal the left behind spouse feels...she really goes into depth and explains the biochemical/brain chemistry of long-term relationships.
There are sound, biological reasons why you are feeling the way you feel...somewhat "addicted."
Text me if you want the name of the book.
I hope you are feeling ok today and got some much-needed rest. :-)
