Addicts that belittle are trying to gain control of your emotions. They have no control over anything in their lives, and are miserable inside. They found that if they berate you, your feelings are hurt, they are able to control you.
Decide whether or not you're going to be controlled by an addict, or stand up for yourself, be strong, set boundary lines and live a life that you're satisfied with.
So, stand your ground. Strong women are very attractive!! And if you still look 28, there's nothing stopping you!!
