Wife just told me doesn't want to be married

[witz10]

So after 8 years together and 2 great kids my wife has informed me she does not want to be married to me and is not in love with me. We have been having problems since moving back to PA from Los Angeles. We came back because we thought it would be financially better and to raise our kids here with our families.
I work for my families mortgage company and the finances have been up and down. She is a psychologist at a university.
We never fought just had disagreements and kept it in. We would have 2 blow up fights a year about family and money.
About 2 years ago she asked to go to a couples therapist and I said yea then nothing happened.
This past Feb we went out on a date and didn't have enough money for a tip this was the start of the downfall. I agreed to go to a couples therapist we went 5 sessions my wife said she thinks we should separate and the therapist said that was premature. We stopped going and I went and found my own therapist to work on my own issues.
I realizd all the mistakes I made the past couple of years between some books I read and therapy. She would invite me to bed and I would stay out and watch tv in quiet. We didn't have any dates for a long time. I also worked a second job and worked on weekends. We drifted apart. Stupid reasons.
I love her more then anything in this worlld. and she knows it. When she ihit me with she does not want to be married anymore that flattened me. As a therapist I would think she would want to fight for us. Considering she works with couples as well. I realize all I did I am willing to do couples therapy, my own therapy ans well as couples retreats once or twice a year just to make sure we stay happy.
Is there anything else I can do. I gave her this website and I am not sure if she looked at it or not. I am currently reading divorce busting and plan on highlighting portions of it that pertain to me.
Any ideas to get her on my side in a way?
