i think he already found someone new. Guys are like that, they blame you for things you did not do, they became fault finders when in the beginning those were the things he liked about you, they get irritated easily and they put the blame on you saying you are quarrelsome when in fact they are the guilty ones. It's just a cover up, he's defensive. Sorry i can't say there's still a chance but who knows, maybe he'll have a change of heart. Everything's possible. Maybe a box of donuts will do, or a surprise pizza delivery. Guys love it when you pamper them. Guys who are not insensitive.
