She feels overwhlemed and crowded

After 2 or 3 dates my girlfriend and I were living together, along with her 4 yr old daughter. the relationship was awesome for the first 1 and a couple months. We did everything together and had a lot of things in common. She recently decided she wanted her old life back where it was just her and her daughter. She says she feels overwhelemed and that her life is not hers anymore.
There is no question that our love is still there. I know she just needs some space and time to realize she wants to be together but also needs distance. I also blame myself for not recognizing this earlier and noticing that I should have not invaded her boundaries. We had a great time together and she acknowledges it. Only time will tell.
