I erased my lab partner's name from the report before turning it in

I did it because I was fed up. Since we started working together I have to do more than 80% of the writing work. I have to remind him that we need to work on the report every single time and he's always late. So we did the experiment together like 3 weeks ago, he hasn't pronounced himself about the report since then. So I wrote the report myself, at first I included his name but I erased it after turning it in. Idk, he write his own report himself too. I'm done, I'm getting a new lab partner.
