Girlfriend went from wanting the relationship to not wanting anything so serious

A little confused right now, because we've been in a relationship for 4 months now and she is just now saying she doesn't want a serious relationship now, because she doesn't want to have to be completely committed to a relationship 24/7. Saying that she would like to be able to have time to do what she wants to do by herself without having to be committed to giving attention to a relationship. We mainly keep in touch on text, so how it was put was more to the point of 'being able to just ignore my phone for a while if I wanted to or spend time with family' not word for word but general idea.

Problem is she never really has that much free time anymore, her family always has her busy with something and so most of the time she can't reply to her texts very quickly anyway. There have been issues like a lot of arguments over stupid stuff like delays in texts, but all in all we've always been pretty close and gotten along great. She said "it's not your fault" and because I asked if there was anyone else she said "there is definitely not someone else" that she just "wants to be alone for a while and isn't ready for something so serious" and "doesn't want to be in any relationship right now", that she "needs time for herself to be free". The stuff in quotes are word for word quotes.

I don't even know anymore. There were always issues with her family, she never really did tell them about having a boyfriend, she always seemed to want to keep me a secret from them, mainly because of how they are and the whole long distance aspect of things. I guess she didn't think they'd be very supportive of someone she met over the net. It just seems really all the sudden out of the blue which is really odd to me.

She isn't really the type of person who would lie, I don't recall her ever lying about anything. She is religious and lying is considered a sin, and she was very strong on not sinning, so she would be honest. I'm just not sure what to do right now. I'm confused and hurt and don't want to lose her forever, but I also can't see how I can just go back to being friends again, which is what she wanted to do. It's impossible for me to go back to just being friends with someone who means so much more to me than that. In the end it'll end up hurting more because of not being together anymore with the person I love. She said she loves me but is breaking up with me, which makes no sense to me. She also said "love isn't always enough". That confused me too. She said: "I don't want a compromise right now, I don't want to give in I just wants this time to myself". She also said said: "I don't know what the future brings maybe you'll still be around when I'm ready but I don't want to take advantage of you because I know I won't be ready for a long time and I don't want to change my mind because I think I'm right when I say I'm not ready for a relationship and I don't want to feel pressured into one".

She also doesn't have any privacy anymore, she used to have a bit more privacy but now she has almost no privacy anymore, her family is almost always around. I don't know if that has something to do with it or not either, but it just seems she had no issues being in a serious relationship with me till just now. It's odd because there was one time she wanted to end it because of some differences but we talked through things and fixed the issue entirely. At the time of that near break up I had stopped replying to her messages for a bit and she seemed very frantic and concerned for if I was okay. This time though it is different. She isn't showing so much the same concern as before if I'm okay. Ugh, I'm lost right now, I don't know what to do. She said she still loves me but that won't change her mind about things. She still is texting me at least once a day but she seems to want to go back to just being friends but like I said, that's almost impossible when I feel so strongly toward someone. The fact that she texts me before I text her also makes it hard to just give the silent technique, because I'd have to just completely ignore her in that case. She didn't really have any real relationships before me, she told me I was the first actual boyfriend she's had.
