Oh I am so angry at your girlfriend. Your father is a BAD person. He abused you SEVERELY and he is STILL abusing you till today. CSA is NOT love. Nothing he provides entitles him to abusing you. You don't owe him anything. You owe him NOTHING. He has deliberately chosen to repeatedly abuse you since you were a young child. Your autonomy MATTERS and I hope people will be able to help you leave this situation.
