My ex girlfriend might have HPD? Or she doesn't love me?

Dear all
I have just broke up with my girlfriend for 2 years. She was moving away only a month, but I found out she started to cheat at least 2 days after she left. She lie about everything that sometime I don't see the reason why she should, eventhough the topic is not about her male friend. She was hot. And I basicly was a nerd with good money. She move right in with me becauase I persuade her too. At first, she has two ex boyfriend attached, one is crazy(in my opinion before) and saying how she is a liar. The second is alpha male who has multiple partner and treat her like $#%^. She took a long time to end both relationshoip and come to stay with me. She change into another woman. She doesn't dress seductive or go out to pub like before. Walk around with old clothes and let pimple grow. Which doens't seem like HPD to me back then. We lived together happily (at least I think) 24/7 for two years.
Then she suddenly change! She gone to some cousin wedding and in within a week she said she had doubt about us. I honestly say that I was stunned. I took her to Rome, Paris etc. Took care of her family when they're sick because I thought we gonna spend the rest of our life together.
Now I found out that she cheated on me with a guy she know for 1-2 months. This guy is alpha male also. She didn't know I know this.
The worst thing about this is, she switch to be the "take care" type to this guys. When she was with me she never actively do anything. I found out that after I canceled the trip we supposed to go together. She book the trip to Paris the next minute with this guy. She find the romantic hotel for him. She would move back into town to be with him and even may have to work harder(which doesn't happen when I beg her before)

I dont' talk to her or accept any call. But I just want to know...
Is this HPD or is she doesn't love me.
Also she doesn't have any close female friend, some male fanclub. I know nothing about her past except for what she told me...

It certainly sounds as if she is treating you with a lack of respect, and that you need to ask yourself where YOU go from here. It will take you some time to mourn and grieve the relationship, and to process all the emotions that her cheating might have triggered - emotions surrounding abandonment, betrayal etc. When the foundations of trust have been shattered in a relationship, the emotional effects can be all encomapssing. Therapy can help you to find a way to move forward.

I am moving this post to Relationships. The issues here seem to concern YOUR feelings, and where YOU go from here. Not all people with HPD necessarily cheat and not all people who cheat necessarily have HPD.

An important component in any relationship has to be honest communication, and when this is compromised or ceases to exist, the very core of what makes a relationship solid and real can be shaken. If you look at the top of the Relationship Forum, you will see a thread about the Seven Stages of grief that people go through after a relationship and it might help you to read this. When there has been cheating in a relationship, the sense of betrayal and abandonment can have an impact on the way the grief is felt and expressed. Therapy can help you to understand your emotions and feelings surrounding this. Please, also concentrate on rebuilding your self esteem. Cheating is never the innocent person's fault, and it in no way reflects upon you as a person. It is important that you rebuild your self esteem.

Thank you for your opinion, anyone else want to add some point that I could answer if she had HPD or not?
She still keep try to contact me. But also saw that she is also lie to the new guy. She talk about some stuff that we did together but instead she refer it as her family activity.

She sounds like my EX HPD/NPD from way back many years ago.

Mine "loved me", as long as she could do anything she wanted.

and treat me like dirt.

$%^&* that!
