There is really nothing to ask. You just described 97% of long term marriages. You weren't meeting her needs so she had no desire to meet yours. The marriage becomes unfulfilling for both parties involved. Usually its just a matter of timing in terms of who pulls the rip cord first.

That's why it's now important to separate the desire for the person, from the desire for resumption of control, stability, in your life. Your brain is telling you that getting W back will restore these things, but it won't.

So ask yourself, what do you want and why do you want it?

“Don't chase people. Be yourself, do your own thing and work hard. The right people - the ones who really belong in your life - will come to you and stay.”- Will Smith
