If your boyfriend is waking you up in the middle of the night because he thinks its funny, he's a major jerk. Whether or not what he's doing qualifies as mental abuse, it's crappy for him to do it and you deserve better. If I were a member of your family, I wouldn't be a fan of his either. That doesn't mean that your family might not be mentally abusing you as well. This is all good stuff to bring up with your therapist I think.
