hi missy,
i dont want this to sound like a lecture. so, will say this in almost clinical terms.
we define how others treat us. your willingness to allow your ex to keep in touch and say what he wants to, and your optimism to try and hear some positive signal frm him has now become the norm of the relationship. thus, while his needs of "chatting with a friend" are being fulfilled, your needs are being shattered. now its time for you to decide whether or not you can play the role of the friend without being shattered. if so, keep going. if not, then clearly to protect yourself, you need to move on and fast.
and incidentally, the forties are the finest age for women. trust me! its a mans thing!!!
smile and love yourself,,,,
