(((((Ali))))) Sorry you are feeling poorly! (I still remember a little English!) I hope you are felling better soon. IF you dont' go on your trip, make sure you are just postponing it, not cancelling it! Travelling when you are ill is no fun, though!
Since you really do need to address the mortgage, how about "I hope you are feeling better. We should talk about the mortgage sometime when you are free" That way you are not putting any expectations onto his return.
