When I read this my immediate reaction (if i were in Pink's position) was until I am your whole world, I'm not interested
Not sure what that says about me but I suspect something, but anyway his actions betray his words and you, pink have had way too much betrayal to need to put up with any more.
There is a strong (and attractive) stance you can take which has the double advantage of also being the best plan for you and your kids.
Have a good and restful weekend
