Thank you everyone for all of your input. Some were helpful, some made me think, some made me attempt to see another view, all were eye opening.
An update:
I did take the lie detector test. I had/have nothing to hide or lie about so that wasn't the issue. My problem with it is the fact that I had to get strapped in and answer questions that I've answered literally a thousand times before. When we went, I had not very much to say to anyone. The man explained the process, even previewed the questions with me before we started. He then hit the start button (or whatever it is) and then started the questions. apparently only a certain number of questions get asked, I think it was 6 questions (could be 4, it's all a blur). I have NEVER felt such humiliation. 38 years old and having a complete stranger asking me about touching anyone's genitals or someone touching mine made me burst into tears. Not tears of being caught lying (because i'm not) but the embarrassment and humiliation. And he asked them over and over and over again. there was 3 stages to the test. The tester even lied himself to "put me under duress" and told me that the lines were inconsistent, and that my fingers were sweating and my breathing was out of control when he asked certain questions. All bull****. I was crying throughout the test and it was a horrible experience. I passed it by the way. The tester told me there were no inconsistencies, that I passed it 100% no problem. I cried the whole 1 hour drive home. I hate him for doing this to me. I understand I lied, and as JackBlack pointed out, when someone is caught lying, then they somehow bring on "wicked" treatment. That's a load of crap. I've been lied to plenty JackBlack, and guess what? I never treated anyone wickedly because of it. I've either worked it out with the other person, and went on with life (and yes, to sometimes be lied to again), or that person is no longer in my life. This person that I lied to 2 years ago, has severe trust issues. I admit I should have never lied to him. If he was the true friend I thought he was, I would not have had to. But that's not how I saw it then, and I made bad choices. I've spent the past 2 years trying to make up for it, show that I'm not a liar, and that I am a good person. This person has put me through absolute hell.
Since the test, he has said there has been some trust gained, but I don't believe it. I still get questioned everyday about infidelity. He says the test only proved that I had not cheated, but that I could be cheating currently. Ah, a technicality.
Whoever said that he will ask for more tests, you are correct! Sure enough, "well, if you are not lying, then you can take another test". I told him no. It was he that chose the questions to ask, not me, not the tester. HIM. I told him he should have ask broader questions then. I'm not going through it again.
Obviously I'm still with him. WHY? WHY WHY? I don't know. He went at me verbally again, and I didn't speak to him for a week. But that was 2 weeks ago. Things are calm for now. Thank you to whoever posted the chart, I'm familiar with it. That's been my life for 2 years. I am at a loss as to why I've allowed this to happen for as long as it has.
Thank you everyone, when I had moments here and there, I would read your answers to remind myself that there are others out there who have experienced similar things, and it gets me through the day. This is the first chance I've had to reply.
I'm looking for a therapist now who can help me, and maybe a doctor too, he can re-implant my backbone when I finally find it.
