broke up and never bpd

When we were dating, she said me she was pwBPD (she said she already tried to kill herself many times and so...). I'm not gonna explain everything cause it would make a huge post, but...
Was she who talked to me for the first time, and said she liked me and loved me. When we were already together, she said I was the rigth person and would never cheat on me, break up with me, or stop liking me. With about 10 or 15 days together, she cheated on me with a guy and a girl at the same day, and acted like nothing happened (I only discovered months after...) and keept telling I was the rigth person and loved me... After 2 months, she cheated on me again and phone called me saying she was so sorry and so, and we got together again. After one day, a friend of her told me she also cheated on me with other guy she didn't tell me, in the same day of this one. And also told me about the first time she cheated. When I asked her, she absolutely said NO, and said everybody was lying. We stay'd together for more 2 or 3 months and then she broke up with me saying I was the problem, and said she have never been diagnosed with BPD. But it looks like she was not diagnosed, but the doctors think she has it. But I don't understand. I also called her mother and told she used to smoke weed, cheated on me many times, even with girls, but then their parents said if I didn't stop calling her, they would call the police or kill me. (I was calling her to make she admit she cheated on me, and she admitted one of them). Her parents don't know who she is, so they believe in her, always.

I loved her so much that I'm really bad now. I can't understand why she did it. I never lied to her or anything, and I really love her. It has passed more than a month, and I can't forget her. I've deleted my facebook and twitter, because it's very painful to see her updates, so I'm trying not to see it. It is really bad to me, because I've never loved another person. She was the perfect person to me

Hi Jamesonhotg,

I've sat here with your post in front of me for the last 30 minutes... I can hear the pain in your post and I'm torn because I know what you have to hear is not what you want to hear.

I'll start by saying it really sounds likes this person is not perfect for you or to you. Regardless of BPD, she has betrayed you enough for me to say you have to find a way through this heart ache and to get over her and not be back with her. I know that is hard to hear and you will probably discount it at this stage but maybe later when you look back it'll make sense.

It sounds like you want answers, and an explanation why or how she could do this... And the reality is you will probably never get an answer from her that makes sense or justifies what she has done. If she cheated on you three times it might as well have been a dozen times. Often we want all the details because we are convincing ourselves that we should take the person back or that they weren't aware of what they were doing... I think it's fair to say she would do this again and again. And you definitely don't deserve that... Do you?

Having said that, You do need to stop calling/messaging her. Regardless of what she has done her parents are likely aware that these phone calls etc are making the situation worse for both of you.

I hope that amidst the pain you can see that this is not a healthy union and you have infact been saved from a lifetime of heartache.

Time does heal some things and I believe it will heal your broken heart too. The challenge will be to not make it worse, focus on learning to be comfortable as an independent person, and seek answers on how to be a better you without her.

Stopthenonesensenow said anything I could have said. I would have been sitting here trying to find a way to say it too, if it wasn't already here.

I just wanted to tell you that I'm so sorry you've been through this. Please, please, please take care of yourself through this. You've done nothing to deserve what you've been through, and even though it's difficult to see this now, she isn't the best for you.
This will be a very painful time, and there is no rush to recover.
I wish you well.
