Answer:
He no longer loves you and your family.
Explanation:
Perhaps he's having an affair or perhaps he's just sick of you. Either way, your father wants nothing to do with you. In a year or less he will have divorced your mother and exited your life forever. Should you try to call him, you'll discover he's changed his number. Should you try to write him, you'll get a return to sender in your mailbox. Forget about your Father as he forgot about you.
EDIT: I just saw that you are not wondering why your father gets quiet and leaves the room when he's angry. You were looking for the linking verbs.
The linking verbs in this sentence are
gets (angry), gets (very quiet).
