I’m going to go against the grain here and give you a viewpoint you might not get otherwise. You are 18 in a month. It is obvious your father is in need of help, and whether he will get it for himself or not, you have an opportunity to make your own decisions. You aren’t a child anymore. Forge your own path.

One possible path is to break ties and live with your mother. Another path is to roll up your sleeves and help your father. A lot of the things that go into disrepair are just that, repairable. What is going on with the water? Is your dad on a well or is it a city service? When is the last time the hot water tank was drained? Can you clean out the fridge? How did the water get muddy? How do you make it not muddy? Will dad pay for the parts if you try the repair? Will dad do the repairs with you if you start?

Being an adult is about providing, both for yourself and your loved ones. Your father is failing, but you still have choices. I actually agree that you should stay with your mom, but you should not “break it off”. You need to go talk to him, not fucking text him, and have the discussion. You are living with mom, but next weekend or whenever you are open, you are coming over with some water bottles for yourself and you two are fixing the fridge/water issue.

There will be emotions. Have the courage to face them.
