Dammit! I bet my bf ate all the food again.
Are you sure your boyfriend ate all the food?
No, I'm not sure of that
Maybe he did or maybe he didn't. Instead of guessing you can ask him directly.
No, I will not ask him. I'm eating next to nothing just to make him pay when he's with me later.
You are hasty in believing he did this without any proof that he did. That's wrong. It is simple to just ask him.
