My boyfriends mother sent me this?

I'm 20 and my boyfriend's mom sent me a very rude message. The subject line literally said "Hey f*g, just thought I'd tell you how you ruined my son." See me and my boyfriend go to the same college and live in an apartment off campus. When his mom found out he was gay she told him that he had to get out of the house and that she wasn't giving him anything towards his college. He had to get a bunch of loans, and he has to work to pay for it. Ever since she met me a year ago she didn't like me. She introduced me to the family as "F*gget". She had sent me rude emails before but I just ignored them and I thought they went away. Today she sent me a email about how I ruined her son and how I'm going to hell and stuff. Two days ago she left me a voice-mail again telling me that I've messed up her son and I'm going to hell. I've wanted to tell my boyfriend all of this but I'm visiting my family and he is vising his and we haven't been able to talk on the phone yet. I don't know what to do. Thanks
