Does she really want to be alone or does she just need space?

My girlfriend of 2 years broke up with me last week it was a total surprise to me because we got along great. We shared many interests and hobbies, and never had a fight.
She told me she’s not happy with the path her life is on now and also not happy with the hour and a half between us but I made most of the effort to see each other because she had fewer days off than me and it was easier for me than her to travel so we got together a couple times per month.
I know there is no one else in the picture, she has a hard time making friends and is very socially awkward which is something I noticed the entire relationship. She had difficulty being affectionate and it was almost awkward when we would hug or kiss like she didn’t really want her bubble invaded.

She has no friends that live anywhere near her Even her parents told me to give her space and let her figure out what she wants. She told a mutual friend (her only friend) that she did not get cold feet and just wants to be alone. But her parents told me not to give up on her yet and thanked me for being patient with her. It’s worth noting she is almost 30 and never had a boyfriend before me.
I have not spoken to her in 4 days and she unfriended me on FB immediately following the break up.
I just don’t believe she wants to be alone forever.
What should I do to convince her not to throw away what we have?

I should add there was no bad behavior in this break up no yelling, a couple tears from her but nothing really bad it was pretty clean because I know not to show much emotion during this time.
I just calmly told her I didn’t want to to end things told her I could make the necessary changes and to think about it she then let me kiss her good bye.
