So I started talking to this guy 10 months ago that recently got out of relationship. Sweet as can be. Nicest guy I ever talk to. Well 10 days later he texts me that his ex came back and he is sorry to drag me into his crazy life.

Several days after he called me to go in greater detail why it happened and that he really did like me but he has to see if this will work out. 

Then a few times after he would text "hi" or "hello" but that would be that. He would respond after I would.

Fast forward 2 months after first meeting him. The ex and him breakup again and it's this backn forth bull shit between us for 3/4 months. 
Dumb me would take him back every time cause he would repeatedly message me til I answered. So I always thought he must really like me, he just confused.

Well finally the other ex ended it for good or i thought. We were inseparable for 4 months. The first month was hell. He was very angry&amp; depressed. Talked about her all the time. Room/apt was a messed, he was eating all the time, even at 3am.
Then a month in. He started changing. Cleaning his room., being nice, having energy and he finally told me he loved me. 

Talked about moving in, having babies. We did have our arguments.. Definitely saw that there was something up with him but I just thought it was depression. He could never be alone, asks if I love him all the time, he could never sleep alone, constantly needed to be held. If I wasn't able to be there he would get wasted or do drugs. So of course that made me feel obligated to always be around.

However, the holidays went so well. He was so kind and loving, no drinking... Telling me he loves me so much &amp; how he wants to move in asap a d he's going to be a better man.

 I really thought his ex was behind us. 
Until 4 days after Xmas. He ended up messaging his ex, hooking up, telling me about it through text. Of course it starts a fight, we break up and now they are back together. He had zero remorse about it. Like I should of expected it or its ok cause its HER and I knew how hurt he was over her.

 He messaged me a week later saying he feels bad, confused, I'm amazing and things now just don't feel right now. 

I told him to never contact me again. That was 3 weeks ago and I haven't heard from him since. He's now posting pics of him and his ex all over fb and all his family and friends are like "wth happened?"

This is the girl he idolize since he has met. She came into his life at a very bad dark time so I don't ever seeing him leaving her. Although he cheated on her their whole relationship. Its like he idolize and devalued her at the same time.

So my question is does he have BPD?
Should I tell him if I ever hear from him that he might have it? 
I don't even know, if he knows he does.
I know he knows something is wrong. He always asks if I think he is crazy.

 I truly care for him and I feel so bad that he is living through this. He always says he how empty he feels inside. It hurts my soul that he feels that way. I just want to help him but I know I can't. Its only up to him &amp; Its not my job anymore.
