You're a Liar and I Don't Respect You

So...if you've been following the roommate story you know all the drama. If not, read previous posts and catch yourself up! So yesterday, Kevin and I did laundry and as I was putting my clothes up he says that our roommate told him he tried to speak to me and I did not speak back. I said, "Oh what did he say?" Kevin stated he said he told you hi and you said hmmm. Now....why would I say that? Wouldn't I be as rude as him if I did that?
I would. And I'm not. Now, in reality, I said Hi. I asked Kevin why would I not say hi? And then I informed Kevin that maybe if the roommate figured out how to talk louder maybe he could hear louder and I'd respond louder. Kevin was not too happy and let me know he asked a question and it was a yes or no answer. It was not but okay. So when Kevin is here our roommate will leave his door open and if it's just me, He walks by, does not talk and goes straight into his room and shuts the door. Oh well. He is not my friend.
Back to him. Why did he lie? Maybe he thought I did not respond but couldn't he say hi again? His hi the first time barely sounded like he said hi, especially to me. It sounded like he said oh so I thought it was nice I said hi! Back to him and lying. Why not just tell Kevin you spoke and did not hear me say hi instead of saying you spoke and I did not speak back.
So with this...I have lost respect of our roommate. It started when he tried to say he is not rude enough and would not have a female over while I have guests in the house so we wouldn't hear him and his women. Don't make excuses. Just tell them to shut up while you are doing it in an apartment you share with people. As a married couple we don't make that much noise when he is here. Then he lied to Kevin and told him I did not speak.
That was it. Don't lie on me. I don't lie on you, don't lie on me! I was trying to get over his wussiness. (Is that a word?) I was trying to get over the fact he got pissed cause I told him to use a pillow cause I don't want to hear him and his partners in the bedroom. I did not even comment on the fact he has multiple partners. I was trying to get over how rude he is as a roommate by not telling people who come over often to say hi or to work on the noise levels.
Respect is a big thing to me. How can I respect you if you don't respect me?
