Shut out, with zero communication

[shut out]

This is a question, I know there is an issue here but I do not know what it is.

For the past 2.5 years I have been involved with a woman, and we were very close.  Talked about future, talked about children, talked about everything.  Had a very passionate relationship.   We had both gone through divorces, so we had quite a bit in common.  We did live far away, but I spent 50% of my time with her, and 50% where my children lived.  We had issues, and it was a struggle but, I thought, we both felt it was worth the struggle.

About 3 months ago she started to question if we could make it work, and wanted things to be "grey" for a little while.  Maybe see some other people, not see each other as much, not talk daily, etc..  I did not like it, and did not accept it well. About 3 weeks into the grey period, I found her profile on Match.com, and wrote her a long letter, mostly chastising my self for not living up to her expectations, and that my life lacked passion, with the exception of her.  The letter was a bit over the top, and i did sound a bit "crazy" 

Since then, she has not spoken to me, only replied to one email (with you are stalking me, please stop) which i am sure had a lawyer on copy.  Now, she knows me quite well, and knows that i am far from dangerous.   I will accept and move on, but would like some closure.

If this was the first time I had seen her do this type of 360 I would not question.  But there are 5 other people who have experienced similar fates.  her brother, who i do not know.  Three people she worked with, who now she does not speak to and never sought closure and her ex husband, who she had physicaly taken out of the house, and does not communicate with any longer.

I think much of this "block out" behavior started after she had breast cancer, but I cant be sure.  How can someone just close the door on someone they have shared so much with, and not allow the other any closure?   Doesn't everyone want some closure?  an explanation of what went wrong?

It's possible she just went off you. It's common and a reason why relationships don't last. Humans are not monogomous, only 3% of mammals are monogomous & humans aren't amongst them.

If she doesn't like you anymore the more you contact her the more she'll think you're a creap or a weirdo. You should have got the message when she said she wanted it 'grey'... that's the polite way of saying 'it's over'.. Sometimes there is no other reason excpet the other party go off you, taste change, in people and in food, think of a food you use to like and can't stand now, or vice-verca and the same applies to people too. It's nothing to did, it's not about who you are or not living up to expections, it's just the way things are and don't take it personal, she wouldn't have had expectation of you, she just liked you and probably when the newness of the relationship wore off, so too did her feelings.

As for closure, you're not going to get it, a lot of people don't get it, they just have to accept it's over for unknown reasons. So it's not wise to look for a reason. Because you'll never know. She probably doesn't even know, all there is to know is that it's over, stop wasting your energies & thoughts on a woman underervant of them, move on, like she has.
