What did that ex do to you? Did she two-time you with another guy?
Fortunately, I did not have to experience that.
However, after the engagement, she became I person that I no longer knew or especially liked (let alone loved.)
I made her pull the plug on the engagement, as her mother had already put several thousand dollars into the wedding, and I wasn't about to let her be the martyr. Mother and I had kept in touch, and she did side with me.
There was a period of about a week we did start talking again. I probably needed some closure, and she was trying to get a foot in the door so she had some options.
One night during a phone conversation, she made a derogatory statement about me that killed any buzz I ever had for her, and I ended it not so subtly over the phone.
I was done. I took the steps to move on. About six weeks later, I met and was dating the woman who is now my wife. She started calling. She tried to engage, and had several conversations with my answering machine (until it cut her off.) She never did show up, I think because she knew that would not be in her best interests.
Later that year, I took another job and moved about three counties away. I knew she was still trying to reach out, because I had relatives call me telling me that she was calling them at work and grilling them in an effort to find out where I was at.
Even though my relatives didn't rat me out, she was still resourceful enough to find out where I was. The calls still continued sporadically (I guess she really liked my answering machine, I was using it to screen all calls.)
To this point, this had been going on for over two years. During the next year, the woman that I had been dating and I got engaged and had set a date for the following year. calls still continued at irregular intervals with messages left. We were married in 1994, and calls still continued through the rest of 1994 and into 1995. We got into Christmas season of 1995, when two Christmas cards showed up at the house. One from her and one from her mother. Both had letters in them, the basic what is going on letter. Hers kind of portrayed herself as busy but lonely. No significant other, bla-zay-bla-bla. My Wife grabbed the letter, and said "I'm going to put an end to this s**t once and for all." She sat down and put together the "Good life" letter designed to make her feel like s**t. My wife then said " If this doesn't work, the next thing will be a hand written Thank You to her for sending you my way." Letter one worked. No more contact. However, it took three years and a Marriage for her to finally get the idea.
That's why I say that the Drama is not over yet for you.
