Is it normal that i want my dad to just leave

My dad gets stressed out or angry over little things. He's seen a couple psychiatrists the past little while. He pisses my mom off a lot and they argue A LOT. He also doesn't really have a close relationship with me or my sister. The only times I ever talk to him is when he asks me about schoolwork and shit. Now I just get annoyed when ever he talks to me.
I really don't like him. Sometimes I do, but the amount of time I wish he was gone outweighs the amount of time I enjoy being around him.

My mom has kept forgiving him over and over even though he's been such an ass for the two decades they've been together. my mom tells me all the time that he cares for me and my sister more than anyone. He's just really really bad at showing it. I actually want him to get leave so he can feel the pain from being separated from the people he loves...Am I overreacting? He was also a piece of shit towards my grandparents even though they visited us just to help in the household. It really got on my nerves.

There was a time a while ago when my dad wasn't allowed to come back into the household for a few weeks. Those few weeks were amazing. He called us often and he sounded pretty broken down about that, but I couldn't say anything to cheer him up because I was so happy he was gone. I was really disappointed when he came back...Is this normal?

I know there are plenty of parents who are way worse than my dad. My dad isn't abusive or anything and he works hard so our family has enough money. I tell myself that I'll get over these negative feelings later on and I'll really appreciate what he's done for me.

I feel like I'm just ranting about temporary adolescent thoughts.
But anyway, is it normal how I want my dad to go away or am I overreacting
