lack of empathy

How does one deal with an ADD spouse who does not show you any empathy.  Thus, for example, when I tell him that I am developing a migraine, he does not respond because he is too busy checking his phone.  Or I text him that I am not feeling well or had a bad day and he ignores it?  I feel like he doesn't care and when I call him on it, he blames it on being busy or having ADD.  I cannot stand not getting any emotional support from my husband.
