Why bother about living with them tomorrow? May happen or may not happen. Why stress right now thinking that way. You have certainly things which are going your way firstly. They aren’t living with you right now. That’s the biggest advantage for you. Staying away means lesser troubles. So avoid phone calls and other interactions. You both are in early thirties and even if you don’t want children now will have to think about future and plan as such for kids. I know a friend before who froze her eggs for future before undergoing some treatment. Maybe you too should think same for yourself and your husband. Plan for your family. Be the supporter and at the same time don’t allow yourself to be ill treated. It’s not impossible. That’s why sometimes being selfish is fine when we don’t have empathetic understanding relationships.
