My husband unexpectedly deserted the family home recently as he wants to divorce me. We have a joint mortgage. I don't think he has any grounds so maybe he is going to wait 2 years unless I petition on grounds of unreasonable behaviour (which I have a strong case for, but I am not psychologically ready to do). He is renting a property. Am I liable to pay half that rent at anytime? Either before or out of a divorce settlement? Thank you for any advice.
