Hi.  I come here often and I value the advice and insights given by people with ADHD and their spouses.  Please help me!

Both my daughters have returned to college and my husband, who has ADHD, is out of town, on his weekly gig of providing care to his parents.  I no longer have a car; all other family members do.  As is typical, my husband does not communicate with me when he is at his parents.  No emails, no responses to emails, no phone calls.  At first, I thought that this was a problem that my husband was unaware of, and so I talked to him about it.  For a few weeks, he made the effort to contact me once each weekend, but he no longer is doing that.  Any tips for dealing with my loneliness and feelings of abandonment?  Any ideas for how to communicate to my husband that it is this behavior exactly that makes me feel like I'm not married and might as well file for divorce, so that I can at least get the advantages of being a single person, along with the disadvantages?  

Thank you!
