No, he's not right. He's a douchebag who doesn't know shit about you or your situation. People who haven't lived in your hosue as long as you have have no right to judge you. The woman's been nothing but cold and or crazy her entire life, and shows no signs of changing. About your schooling though, is there some way you can pretend to be your mother, have somebody else pretend to be, or something like that? Since it's an online course, I'm assuming these messages are sent online to somebody who's supposed to be your mother, which to me means it wouldn't be that hard to fake.
