First of all, as Ryan stated, that's the mother of your children. I understand that you may be upset that your ex-wife, who comfortably embraces her sexuality, left you after you decided to cheat on her with a pair of twins (Don't worry, that doesn't make you a thot, Wiz- you're a guy!) - but firing shots at her in a public format, one that your child will hear one day, is not the way to go about that. It's sorta funny, because Wiz absolutely
loves to show off how great of a father he is on Instagram, yet seems to have no real consideration for that in the studio.
Amber did nothing except take care of her kid, be a good wife and look damn fine while doing so. Wiz loved that back in the day- but now that he's not with her, he's tripping all over the place. Honestly.
Couples that had kids should try and be as peaceful and respectful as possible. Unless one of you did something awful (ie. abuse), keeping that relationship is very important.
