Could you ask your ex to bring you a bouquet of daffodils, to brighten your room? Maybe try walking around your room and doing some gentle stretching ? Their are apps ( Calming App ) etc, that could help you relax. If you have a smart phone, you could listen to Pandora, or downloaded music, by placing the phone under your pillow....like your own soft speaker
I think it's clear you can't count too much on your husband, which is a terrible shame, but you're strong.
