Symptoms of bipolar disorder?

At the beginning of December, my neighbor started hitting on me big time. I tried to ignore it and shoot him down as often as I could and he'd apologize, say that he had let himself out of control and please don't tell his wife. Eventually, I had to tell my sister (it's her son's grandpa) and she had to tell him to stay away from me. And he did. Until Saturday. We had a conversation about my husband's mom's vehicle that needs work...my neighbor is a mechanic. Out of nowhere, he asks to come over and play the wii. I lied and said it wasn't here. He asked if we had other play systems he could play. I said no. He asked if he could come over and talk, I said no. Then he asked me to delete my text messages so he wouldn't get in trouble. I said no simply for the fact that my phone broke last week and I'm using someone else's until I can get a new one and I don't know how to work this one very well. He told me to do a mass delete of all my text messages. Which I refused because there were some important ones that I need. This went on about ten times and then he started talking about all the people that would be hurt because I was being stubborn. I tried to ignore him and then he got nasty. He said (quote) "Well I wasn't gonna say anything about what I know but we'll see after this." Which in my book is a threat. I was completely confused about what he was talking about...what could he know about me that I don't even know?

I sent my sister a message and told her what was going on. She talked to him and told him to stay away again or his wife would get involved. He told her that I would regret ever talking to him that night. Which trust me, I do. I called my husband up at work and told him what was going on, which I wanted to avoid as much as possible because he has a temper and I don't want to feud with my neighbors.

The next day, my husband sent a message from his phone asking what the big secret was. It took three hours for a reply and the answer was, "Ask her." I had been worried that he'd make up some sort of an affair between me and someone else but at this point I figured it was just all empty threats. My husband replied back, "Obviously I have." And my neighbor went into a spew of how I had tried to come on to him at the beginning of the month and I had taken conversations with him too far. My husband replied back that he knew about what happened the first time cause he had already talked to my sister. So now my neighbor was caught in a lie. So he changed the story to my husband needs to keep an eye on me because I'm not faithful. But don't worry, he'd never do anything with me. He values his marriage. Which again, my husband called out. I have 5 kids...if I was having an affair, I'm sure my 4 or 5 or 6 year would spill the beans.

Then my neighbor switched gears and said that the way I act on my computer (facebook) was proof of my lack of morals. Which I suppose meant when I updated my status (which has always been random things...baking cookies today, kids are fighting today, flu bug is in the house.) Anyway, my husband replied back saying that was easy for him to check because my pastor and his wife and half the church are my facebook friends. So once again, caught in a lie. Then he pulled out a doozy. "Well, every night when you go to work, Officer ***** is at your house and he stays until right before you get home." So there was the accusation I had expected. This officer being an old family friend my husband knew it was a lie. Not to mention the fact that they work similar shifts.

At this point in time, I sent a message to my neighbor's wife saying we needed to talk. She instantly guessed why. Apparently every year in December this happens. He has actually cheated on his wife 5 times...and always with one of her friends. The doctors say it's a part of his bipolar disorder...at least going out and having affairs is. Lucky for me his wife told my husband her husband was crazy and he made it all up. Problem is it doesn't change what was said.

She apologized to me and so did her son but he hasn't even tried. The way I understand it is he's passing it off as okay because of his bipolar disorder.

I don't know a lot about bipolar but it just sounds like an excuse...sure he tried to get me to let him come over, presumably so he could try to have an affair...but threatening me, and implying I'm a wh*re, and flat out naming someone that I was having an affair with!!! I don't buy it. This could have done serious damage to the officer's career!! It's done serious damage to me because of an unpleasant past that I won't mention here. So could someone explain?
