13 years and two small children

[Hurt213]

Am I dealing with a wayward or a WAW ? I don't really know how to tell..

Judging from my info posted so far, is this "relationship" totally doomed and should I just say goodbye and thanks for what was ?

I feel like fighting for this relationship though... she wrote today, calling me nicknames and acting all happy and friendly - All i could think of was that this morning, she didn't say good morning, however i woke last night from a shadow in the hallway, she was apparently looking at me and my daughter sleeping (she didn't notice I woke) she stood there observing us for 2 minutes after she came home from OM, before she silently went to the other end of the house to go to sleep - meaning of this ?

I found a old letter she wrote me 10 years ago, where I was about to leave her. She pleaded, begged and cried her heart out, asking for us to reconcile, and talk about things, not make hasty decisions and what not. I printed this out together with a letter stating, that I am going to be moving on now for the sake of myself and the kids - I have tried to reason with her (my bad), but she clearly does not see anything as long as OM is in the picture. I told her that multiple times in the past where one of us had found another, destiny lead us together again - always the same pattern - However this time is different since we now are selling a home, dividing the kids, and breaking a lot in the proces - I don't know if we are able to get back even if destiny shows us the way when her rebound ends - I am going to give her the old mail together with this letter tonight.

Help is appreciated
