Parents and boyfriends

Hi ladies, i'm in a bit of a situation. my father doesn't like my boyfriend at all, after he found out i got pregnant (didn't have the baby) by him he absolutely hates him. he didn't know that i was still seeing him until recently. i'm 18 and still live at home however my father is very controlling, more like his way or no way. he told me that he didn't want me to see him and if he caught me with him it would all be over. i love my father to death and obviously don't want to lose him, but i'm in love with my boyfriend and don't want to lose him either... idk what to do.
