Stop helping her with the bills. Get some sort of formal agreement in place if you are not ready to file but STOP helping her with bills and tasks. You are giving her the best of both worlds so why *would* she want to change anything?
Ever stop to think why you are good enough to pay her bills and do her handyman work but you are NOT good enough to go to dinner with or talk to?
Her saying she "eventually" might want to work on things is a fancy way of saying if nothing else pans out or her financial situation worsens she might give you another shot.
Marriage is not about "eventually". You are in or out. If you are out that's cool but gone are the perks of marriage (help, support, money).
