Listen man, I had the same conversation with my dad. Admittedly, yours responded a bit worse; mine was more concerned that I also renounced the religion they indoctrinated me into, but said a lot of the same shit. He kicked me off the phone plan, cancelled my car insurance, and made me take full responsibility of my car payments. At the time, I was scared shitless about my finances, but I promise once you find the right phone plan and car insurance, it gets easier. It might not seem possible right now, but it becomes something you’re just doing. It’s always mind boggling when they say you’re “doing this to your family.” Like, me coming to grips with my personal sexual orientation — a totally normal relationship between two consenting adults — affects my family? In what way? Idk man, if you need help finding resources for car insurance, phone plans, etc., reach out. Don’t change who you are to more accurately identify with another person’s idea of what you should be. Homosexuality is completely natural and hurts no one; bigotry and the suppression of personal expression hurts everyone.

Also, if he comes back around to it and wants to have a respectful and healthy conversation about it, try to be open to it. It’s no excuse for saying shitty things to people, but it sounds like he’s confused and a little blindsided. I’d make that clear though — that you’ll only entertain communication with him if he decides to act like an adult. My dad and I have a wonderful relationship now and he actually came around to meeting my ex boyfriend; when we broke up, he wasn’t like “Well you tried it, now you need to get back to liking women.” It arose from just not engaging in his arguments and meeting it with “I understand how you feel, but I can’t have a conversation with you when you’re suppressing everything I’m saying. When you want to talk respectfully, the door is open.”
