My guy friend mother told me off HELP!!!!!!?

friends 56 and I 56 talking, after a year. I've seen him 3 times, slept with him 2. His mother husband die wanted the son to live there. We always talk on the phone, she could hear him talk, were 1 hour, 20mins away. I have good intuition about things. I am trying to help him over come women. I try to get a hold of him, decided to call his mother thinking the phone is mess up or at least home, BIG mistake, after she found out it was me. I called 3 time in a year. I never met the mother. She said with rage, it was like the devil himself. "K don't like you , stop bothering him, why do you keep calling, don't call any more, you know he has problems, psycho, stop calling, check your crystal ball, hang up". I was in tear, after that he called, said "did you call?", Didn't have any idea what happen, the connection was bad, but he understood, then got disconnected as his cell phone does that. I tried to call him back many times, that night, didn't pick up,wrote to him on e-mail many times, for an explanation. I was confused, before this I was getting mix messages, it was a love and hate relationship, it would always be O.K at the end. He would always talk to me, everything was fine, that's the last time, the only thing he wrote was "Stop calling my phone. I have enough crap to deal with right now and im fetting mad", I didn't do anything and everything was fine until the mother told me off. What does the all mean???? still confused. I don't understand. He won't explain or talk.
