Do I have the right to be mad at my dad?

My dad has been hinking of me differently since I started to have a boyfriend which was like 1 year and nearly 2 months ago. All of those time I tried to make him see im still me just with someone who I want to be. He looked down at me since and started to be even more protective, but recently my mum had a go at him because my boyfriend is getting all stressed out and depressed because of his school work, own family problems and now my dad is making him even more depressed because my boyfriend has the fear that my dad will stop me from seeing him, my dad has always been giving him evil looks and looks down at him like his like the other guys [cheaters]… he also said its because we’re too young, im too commited in ONE boy and that he isnt a christian. I have tried to balance things out between them and always tried to get along with my dad, but since this Wednesday I am thinking of him differently. Wednesday was our prom day and my dad didnt even bother to see me in my dress… He didnt even came home to tell me to enjoy myself but instead he avoided me and my boyfriend. Me and my mum has been waiting for him to come home, but he didnt turn up, so my mum dropped us off in school and as the night ended my mum picked me up and said that my dad went home after we left the house and went straight to bed.

Today my boyfriend went to my house to speak to my dad and he actually had the courage to speak to him finally but my dad avoided us and refused to look at him, we were at the lounge talking and my dad came down and went to the kitchen and waited there until my boyfriend left!!! and then I went in and my dad had the courage to ask me questions why is he here and why was he here for that long! I was upset with him, I ignored him and closed the door. Im mad as he never even talked to me since my prom and never said a word! and thats all he had to say to me! Do I have the right to be mad at my dad??? [he’s also probably reading this as he goes through my stuff…]
