Hi Sandi,
Just thought I'd drop in to say hello, sorry if I'm imposing on someone elses thread.
No big news from me, I have the D papers from my W, I need to review them and sign and return them to my wife so she can give them to her lawyer. She has not requested any more money, of course she has already received $125K from the refinance of my house and split assets.
I wrote her the note I said I would write, I told her how important she is to me, I said she is the most kind & considerate person I have ever met, I told her she has a warm smile & eyes that sparkle. I told her I was lucky to have her and the 17 years of memories we have together.
I told her I was a happily married man (something she has brought up, thinking I was not a happy guy?)
She thanked me for the letter about 3 times, but her goal is to get a D, she told me she wants to be by herself, I asked her if she's lonely since our S lives with me. She said she is not lonely, she likes living by herself, she said she doesn't want or need anyone else. I still wonder if she is going through a MLC? Other times I feel as though she just wants out and doesn't want to be a wife anymore, I think that is most likely.
Thats my update, please feel free to give me your thoughts.
Thanks
