Yea, I am in a similar situation. D has not been brought up yet but S has.
-Stay active with your children (they give me strength)
-Don't focus on your W (she has to decide)
-Make your interactions with her positive (do not look needy)
-Get out, have fun, do somthing that you have been holding off on
-Fix your issues with "lies" and whatever that implies (hey man we all have issues that need to be fixed - get help)
-Stay strong, you need to be a good father and that means keeping relations strong with your wife and if that does not work out then building a stronger relationship with your next partner.
-Good luck
