No one owes you anything, and no one can give you everything from the very beginning. Everything he does is just to make everyone in this family happy and joyful. If you truly think this is what should be done, then you've misunderstood everyone's intentions.
"Since you've already said it yourself, that man has explicitly told you he has no feelings for you anymore, so why do you still wholeheartedly think about being with him?

In your heart, have you never regarded me as your husband? Does the safety of our family mean so little to you? Where do you place your family? Since you initially chose to build a family with me, you must take responsibility for it. The way you are acting now, what do you take each member of this family as, mere pawns to be discarded if unwanted?"
