Is it normal that my sister doesn't want to talk about her problems?

My twin sister had been with this guy for almost 6 years, and whenever she was unhappy with the relationship she binge drinks for the whole weekend and pretends everything is okay. It came to the point where she barely went to go see him or spend time with him and opted to go drinking with her buddies every weekend. And all she ever tells me is that he never wants to do anything, but to my knowledge he wants to save up money and move out of his parents basement. So they usually end up staying at his place whenever they hang out.

Anytime I ask her "So, how's everything" and vaguely mention that I'm open to talk serious, she gets angry and quickly changes the subject or tells me (almost all the time) she doesn't want to talk about it.
She had gotten to the point where she threatened him that she would commit suicide and I only knew this because he messaged me on facebook.
He has messaged me a couple of times concerning her, and those times I told him the same things. She won't talk to me. She won't open up to me.
She's always making him out to seem like a bad guy, but he's always so concerned for her, even if he grew out of his feelings for her.

We used to be so close before we hit high school.
But now that they're not together she still binge drinks and has even started going out on weeknights and she still seems "okay". She seems to really enjoy seeing her friends more often. I just don't know what to do. I don't want her to feel like i'm prying information out of her. And I don't want her to feel angry towards me for being concerned.

Is this actually normal, for her to not ever talk about something that's troubling her?

    Not everyone wants to share their problems with others, and not everyone will ask for help unless they want it.

      It's been this way since around the high school days. We're 25 now, and I've never felt so detached. I have a broken family since forever and she's the only family I know that understands English and can assimilate.

      I found her in my closet with a note and a knife 5 years back because of her caring for this guy. She didn't cut herself (thank god). I just heard crying in the middle of the night and even then it's just vague bf bashing.
      I don't want to sit back and wait til her deathbed to tell me that I should have been there for her.
      I don't want to feel like I'm giving up by just leaving it alone. You know?
