And that's why you have to seriously consider staying. It's for your daughter. My guess is that you'd like to raise her. Also, if you were to leave, what kind of Sdad would your wife bring in the home to help raise her? Your SS might have gotten lucky getting you for a SDad, but your daughter might not get so lucky. I've seen some ugly stuff amongst friends going through divorce.
As far as your wife, If I were in your shoes I'd want to pull in the purse strings pretty tightly. You mention that you believe she's just staying with you for financial reasons. Well... start a new bank account in your name only and and don't add any more to the joint account, or a very limited amount (if you have one). Start separating finances (not for divorce, but just so you have more control)...
There is no arriving, ever. It is all a continual becoming.
