Thanks for the advise. scottyg. As usual, he acted like nothing was wrong. I was clearly upset, and he seemed unphased by my demeanor. He made excuses and tried to put it back on me for not calling. I told him that when he drops off the face of the earth it hurts me and it hurts our relationship and I am a big girl and can handle about anything, but silence. In the past I have held back and not told him how I feel but that isn't fair. I can't protect him. I have to tell him how I feel. I have to tell him how his actions impact me. Now, only time will tell, but I can't tolerate the unhealthy behavior anymore.
I have other concerns, but one at a time. I will encourage him to get connected with MS.
