Save my marriage to w she is moving on

[ugetvince]

Its been a bad weekend. I already know what everyone is going to tell me but here I go.
First ive youve kept up with my sitch you know I ahd some major medical issues this past week. Ill know this week about further surgery but I think ill be okay.
If you read my prior post my w came aroung the day after my surgery but then a few days went by and I didnt hear from her again.
On friday I had to go back and forth to the court to try and file paperwork to my wife 30 seperation notice. At the end I find out that nothing acutual been filed because she failed to pay. Mentally I was not all there and feeling pretty shitty physically and mentally.
Then I get a text from w about dropping off the kids and if I cant handle them she would be willing to switch weekends. I was at the Doctors office when I got this message. I didnt want to rspond but mt emotions got the best of me and here is the convo that took place.
I wrote something like just left Doctors office youve no idea what Ive been thru this week. I hope you can look yourself in the mirror and be proud of the person youve become because I dont know who you are. You havent even bothered to see how im doing or find out about my test results?
She wrote"Remember this message the next time you have a breakdown. This is the reason I will never be with you ever again."
It got even worse from there with a couple of messages back and forth her last one stating. I guess you know how it feels now. u just see life as it is for you now. I tried to be there and got nothing in return."
The texted stopped and all conversation have been only about the kids. Back to square one. Ive been doing so well but I dont know how to move forward and act like nothing bothers me and that i shouldnt wonder were my w of 7 years shouldnt have some feeling of love and compassion. I know I shouldnt exspect that but I feel like im chasing something and I dont want to chase someone that doesnt even care about me anymore. Please advise
