I am going through this right now..but it's the other way around...My H is in another state visiting his mother, sister and brother-in-law for 1 week. I couldn't get the time off.
We have talked often throughout the day and that keeps me feeling good.
Also, I am doing things that I like to do...I stained my bathroom cabinets, visited my mother and sister for some girl time..and made plans to have dinner with a friend. Work takes up some time too.
I would make use of the landline and talk to him as frequently as you need to.
Also, soak up as much love as you can from your family. My family, as of recent, now knows about the A...H and I went through a rough patch..(see my updated profile)...so they have been hugely loving and have given me so much strength. I'm so grateful for them.
Is there any chance that you would share what you've been through with them?
I only did because of our most recent crisis, but I feel pretty relieved now having them there whenever I need to talk etc...
