I want a clear answer about whether we are still friends
What happened, why are you unsure about your friendship?
I would like to know if he does love me or not.
I understand your want for more information. It is easier to get along and operate if everyone is on the same page.
I'm going to get my answer, or he's going to pay for his indecision.
Whatever answer you are waiting for maybe something that he is not sure about and I do not think it is okay for you to threaten him that he will pay unless he gives you an answer. He may be conflicted about his feelings for you and it is not nice for you to force him to say anything about it. If you really love this guy, then you should be patient or at least move on to other people if you can't wait for him.
