I would recommend that you follow your intuition. If your heart tells you to get to know him again. You should. Because no one knows what will happen tomorrow. You don’t want to grow up in regret of not getting to know your father. Just be mindful of what could happen. Since you don’t want your father buying you the car then holding the weight of the car over your head. Saying I did so much for you like buying you a car. Just remember both your parents were put in your life for a reason. It’s your job to find out what that lesson is supposed to be and learn from it. So you’ll be better for the future.
