I like it. It's sweet, and I like that you tied it to father's day. I also like how you describe your dad. It shows how you remember him. He's taught you those lessons that are hardest to learn. Pick yourself up when you fail, even when you think you can't, and I see that you appreciated him for that. It works well.
However, you lost me a bit at the end with the last few lines. I get why you hate that you love him, because it hurts to love someone who is not here to hug you, but your emotional convictions from the first few lines was lost in that last bit. I think the last line ties it all together neatly, but maybe look into "But I have something to say to you" and change that around a bit?
Other than that, it's really great! I liked it, and it is very touching. I would just drive that emotion home a bit more? (Or disregard all this as pure nonsense :-))
