He already made his decision by getting involved with this other woman. He already showed you how little respect he had for you and only thought about himself. Do you not think you are worthy of respect? Do you see yourself as unworthy and undeserving of being valued that YOUR feelings should not matter? He is NOT thinking about you OR your feelings, he is ONLY thinking about himself here. That is actually what he is ALWAYS thinking about in the picture himself and HIS OWN NEEDS.

Even your thread title says it all. Why do you think he should have all the power and control? When are YOU going to have a say in this relationship?
