How to tell my father that I have a boyfriend

My father and I dont have a close relationship and he can be a bit overprotective sometimes. We rarely talk, he only calls me to ask if I passed my exams at college. It seems like that is all he cares about. I have been dating this guy for a while now and I dont want to lie to my father anymore. I have told my mom and I have been dropping hints for a while. She wont tell him because she doesnt want him to bug her about it. I understand that he might be against it because my boyfriend is 5 years older than me and he never met him. I get where his anger and worry would come from since I am his only daugther.

How do I break the ice and tell him without making him upset? (I am 19 years old and attending college at different city so I dont live with my parents anymore)
