Is this guy Borderline/ Bipolor/ or just a nut?

I have been working with a guy for the past 6 months. For the first 3 months we didn't seem to have any real interest in each other, but all of a sudden he started showing interest in me. At first I was really surprised because I just don't seem like his type, but he pursued me a lot, and I was apprehensive because he was my co-worker, and he just wasn't my type, and was 33 and never married or no kids (I do have 2 kids) also because he had been in rehab 3 times for drug use, and because it was obvious to everyone at work and myself the guy has issues. At work he is a drama queen, power tripper, has no regard for anyone else, makes plans and continuosly stands people up, is very aggressive and pushy with people, has lots of insecurities and needs constant ego stroking. He also skipped work a couple of days saying he was depressed and wanted to kill himself. But he kept persuing, and I finally relented, telling him I didn't want anything serious, since I just got out of a very abusive marriage I thought "why not, I'll have some fun, what could it hurt". Weeeellllll, from day one it was dysfunctional, after sleeping with him the first time, immediately after, he locks me in his backyard, for about 10 minutes. I didn't know how I was going to get out, when I asked him about it he said he thought it was funny. I went off and said I didn't want to see him anymore, but I see him at work every day, so eventually he kissed up and got me back to seeing him again. The entire several month relationship was this way the whole time, mainly that he really likes me and is very sweet until I am seeing him and then ignores me and is rude all the time, til I've had enough, quit seeing him and he starts acting like he likes me again all of a sudden. Towards the end of the relationship he started telling me he was in love with me and pushing me to say the same, but then would turn around and act like he could care less about me half the time. This goes on for several months, til I had enough and was so mean to him when I broke it off, no one would have wanted to date me again. He still constantly does things like provokes reactions out of me, or tries to, and tries to pit me and other girls against each other. He admitted to using drugs while we were seeing each other which could be the problem, but I don't think that's the entire problem. We have been not seeing each other now for about a month, and have been friends, he calls me today and tells me he has been considering becoming gay, seriously. I was very upset about that, which he cannot understand why. He has admitted to me that he has seen a psychologist and he knows he is a chaos addict, but there has to me much more than that going on here. I wish I could completely cut ties with him, since I care about him and find it realy hard to, but we work together, and are dance partners. Now this morning, after our blow up he's supposed to be practicing with me but he's sick and wants me to come over. That's pretty common, during any disagreement, he never apologizes or anything, he just pulls some guilt trip over being sick or something. Some background I have left out....this job is the longest he has had a job(we are dance instructors), he still lives with his mom and she does everything for him, he is constantly competitive with our boss, he has told me he is a compulsive spender as well, and I noticed that his communication skills are atrotious. Anytime I tried to talk to him about a problem I had with him he would get angry, yell, and say I was the one flipping out. I have also noticed that I think he says and does a lot of things to make me mad on purpose and he has made comments that when I have been cranky that he likes it. Any suggestions?

Sounds to me more like NPD than BPD or Bipolar, but I'd guess the psychologist that he saw is the only person who might really know. Most of all, though, he sounds like a total douche. You're no longer with him, so you don't have to put up with his crap. Set boundaries and enforce them.

I have considered that because of his complete disregard for others, but when he acts like a jerk, and I get mad and tell him to screw off, he starts the graveling, I'm a jerk and messed things up routine. He also is pretty candid quite a bit about physical insecurities he has, so that led me to belive he's not NPD. Although he does act like it sometimes. Honestly the stuff he pulls I see as more that he likes to constantly get reactions from people, either that or he just likes the chase and once I'm hooked looses interest.

hi,
you need to keep being yourself,EXCEPT thinking of others!
you have wise to keep in mind, your have as a mental illness.

So many people look at DID and do not understand.
if,
only if you have such trauma in your life you will split
I have never met someone who was just : born with it.
Though I don't say it could not happen? trauma is the main source.
NO ONE likes to be called a "NUT".

peace to you,

I bet he wouldn't like being called a nut, anymore than I don't like being locked in his backyard or told I can't come over cause he needs to spend time with his dogs. Guess I should have more consideration.
