Cut him some slack. To raise a daughter on his own would have been incredibly tough, and he is incredibly protective and can't bear anyone to hurt you. This is, I am sure, done from love. It also explains why to think of you as a sexual person distresses him - he knows what teenage boys are like, and how they often treat teenage girls, and its not pretty (YMMV).

Also, he hasnt been dating much, I think TOO much of his life, hopes, expectations, dreams, are tied up in you. Thats why he freaked about nursing versus law.

But, nevertheless, he needs to gently relax the reins. You will be independent one day, and you need to prepare for that in baby steps.

Regarding college: yeah, well, OK, if he isnt paying for college, and you are, then he DOESNT get a say in it. There he is being an asshole, pure and simple. I mean, sure, by all means give advice.

Ideally you sit and talk but he doesnt seem awfully good at that. Is there some other relative you can get on board to speak for you?

BTW, look forward to when he is old, and you loudly say in front of the nurses in the care home "What was that you said about nurses, dad?"

TLDR: college is your ticket out. Get prepared for financial independence.
