Grits just said the "s" word--stalking. Worth saying a word or two about.
Regardless of good intentions, repeated contact after someone has told you to "please STOP" can be considered stalking. We tell people here on SR all the time that when the alcoholic refuses to leave them alone, in spite of requests that he do so, consider getting a protective order.
Felicia, I know you care about this guy, but he has a RIGHT to be left alone. He has avoided your calls, ignored the card that you left for him (walking four miles to deliver it, I believe you said), and you were considering calling his lawyer to get information about him AFTER he has asked you over and over to move on.
Now, if you really do care about him, I suggest you respect his wishes. Even if your behavior doesn't QUITE rise to the level of stalking (I doubt he's afraid of you), most courts would consider it harassment. Please show him the same respect you would want someone to show you if you asked them to leave you alone.
