Is it possible that my partner has borderline personality disorder?
	
	
		I have been with my partner for three years now, and everything is OK, except lately he lies about every little thing. Then he says he he didn't say it or do it.
Example #1: One day he told me he bought me a coat and when I saw him I asked him for the coat and he said he didn't say he bought the coat he said he was going to buy the coat! Clearly, he was lying, I told him that is not what you said and he denies the truth.
Example #2: Last month he had washed his daughter's hair and I asked him if he had blow dried it.  At first, he didn't respond to my question, than he said, out of nowhere, "The only B**** I have my daughter around is the one who does her hair". Which I took offense to, because I don't see his daughter when he has her.  So, I felt like indirectly he was saying her mother is the one that has a say-so about his daughter's hair, and not me.
I questioned him about that nasty comment, and he said that is not what he said.
I don't know if this man is playing head/mind games with me, or if he is battling some type of disorder, and he can't help himself.
