Why would an abuser threaten to dump you and give you the silent treatment when you told him you are going to go to college after staying at home for ten years?
Abusers seek control over their victims and he's had 10 years of controlling you. For some reason you are finally seeing the light and moving on with your life and your abuser is uncomfortable because he knows once you leave or even go to college every day and come home he's lost control of you. His only option is to threaten to dump you (scare tactics) so call his bluff and hope he does! I admire you so go for the stars and keep going! Good luck
