Need help understanding, is this part of Bipolar?

Hi everyone, I have a questions about Bipolar Disorder, and I'll try to make it as short as possible.

First I'll have to start with why I am asking these questions.

My Wife and I have decided to take in one of her coworkers as a tenant, things were great at first.

Within the second month he started manipulating my Wife to buy him things. He would ask her to buy him stuff, and if she had any reservations about it he would use emotional manipulation to pull at her heart strings, he would say things like " I need this" or " This will make me happy" and if that didn't work, he would get angry and be passive aggressive and threaten to end their friendship.

If she said that we wanted to talk to me first, he would convince her not to.

He manipulated my Wife to the point where she maxed out four of our credit cards in one week buying him new furniture, two televisions, etc, etc. And when she told him she was going to tell me, he would continue with the guilt trips and get angry with her.

I found out eventually she maxed out the credit cards, the total was over ten thousand dollars, at that point she had to come clean to me about it.

He got mad at her because I found out, and I tried to put a stop to her spending any money on him.

He would treat her completely different, he would use these manipulative tactics on her and he would never do it with me. He would ask or demand things from her, and he does not want her to talk to me about it, and he never talks to me about those things.

A new example is that he wants his boyfriend to move in. My Wife and I agreed that if that was to happen, rent would have to go up. Instead of talking to me about it, or both of us together, he only talks to my Wife and tries to manipulate her into not raising rent if his boyfriend moves in. Well, I put my foot down about it.

We are at the point where we are going to kick him out on the street, he has cost us thousands of dollars and we can no longer take the manipulation.

These are my questions:

1) Is emotional manipulation intentional or not intentional a byproduct of Bipolar Disorder?

2) He is horrible at managing money, he has a compulsion to spend money. He says it makes him happy. Is that a part of Bipolar Disorder?

3) He obsessed with filling every corner, every inch of his apartment with stuff. It's like he is a clean hoarder. Oh, and he is obsessed with the color silver, he would spray paint everything he has silver.Is that part of Bipolar disorder?

He claims he is Bipolar, however I think there is something else wrong with him. yes, he goes from happy to sad, to angry at the drop of a hat. However, I wonder if he has other underlying problems.

Hard to tell unless you're a psychiatrist. Thankfully I'm an armchair psychiatrist. Sounds more like a personality disorder to me. I'd be more worried about your wife being so easily manipulated.

The only point that is definitely a symptom of BP is the spending money.

Everything else you listed is just personality type.
