Is this a long time to still be angry after fight?

Me and my partner had a fight 11 days ago now. We both were in the wrong and both apologised to each other. I’m completely over the fight at this point but my partner is still cooling down. I’m getting frustrated with him a bit because I feel like it’s a long time especially when I’m over it and want to forget it.

He just says he finds it hard to move on from fights and let things go. He also won’t have sex with me or any other affection while he’s annoyed. Am I wrong to feel angry he takes so long? I can’t forget about the fight because he’s still sulking about it, it just drives me crazy.
