She pushes me away because I love her way too much? 10 points for best answer.?

[107]

So me and this girl are in love with each other, we aren't committed yet, but we do really love each other a lot, we just are taking it slow.
One day she got really upset, said she was about to deactivate her facebook, and removed all my comments from her profile.
Later she became perfectly fine, but I was hurt. After inquiring why, she told me she sometimes feel the need to push me away, because I love her so much, and she is a bit scared, saying she doesn't want to hurt anyone.
Does this imply her feelings are less for me, or she would perhaps be with another guy, or like someone else?
She just told me that she does think I love her way more than she does, but then went on to say this happens to her every time she is with a guy... Can someone explain further?
