Aww sweetie..that's just his one and only way of lashing out at you. Please don't take it to heart..from what you've posted he loves you he was just mad. I know it don't make you feel any better about it all.. but just try and stand your ground and head high. Kids say mean things.. I know I've had my share with my own son..so here's a hug for ya and maybe talk to Richard about it.
*hugs*
