She may have felt like she was really into you at the start but has now become more anxious.
Now that she has had the opportunity to get to know you better, she may be learning things about you that are giving her pause.
These may not necessarily be bad traits.
However, they may be personality or background traits that she is trying to find ways to reconcile with or relate to.
If she is having a hard time doing this, she may get to the point where she tells you that you are both moving too fast.
Even though she initiated everything, she didn’t necessarily know that she would encounter this issue.
When she initiated, she was acting out of an immediate emotional impulse.
It may have been driven by physical desire.
She may have felt that initial powerful physical connection with you and didn’t think about anything else but being with you because she was so smitten.
However, now that she has had an opportunity to really interact with you, there may be these issues that have arisen that she is worried about.
She may not know whether she can go through with being with you if these differences aren’t compatible.
This may be why she wants to now move a lot slower than she was moving at first.
If she is to dedicate her heart to you, she may want to ensure that it is in good hands.
She may not want to put herself in a situation where she develops feelings for you only to have them ruined by some kind of behavioral or background difference.
Another reason why she may have told you that you are both moving too fast even though she initiated everything may be because she may not know what kind of relationship she wants at this time.
She may have never actually thought this through.
She may have initially made a move on you because she wanted to be with you intimately but may not have thought beyond that.
She may not have truly considered whether she wanted anything more substantial.
At this stage, she may be thinking about what it would be like to be in a relationship with anyone and may be worried that she isn’t quite ready for this kind of responsibility.
She may even be more worried that now she has had some interaction with you, she recognizes that you may be the type who falls quickly and falls hard.
A part of her may find that endearing but another part of her may worry that she may end up breaking your heart.
She doesn’t want to be responsible for that.
She wouldn’t feel right.
Perhaps she hoped that she could have kept all of this casual until she figured out whether she truly wanted a serious relationship or not.
However, she notices that you are so into this and may be worried that your emotions are going to get the best of you, thereby leading you to want something more substantive with her when she hasn’t even come to terms with what she truly wants.
She doesn’t want to be in this position and so she tells you that you are both moving too fast.
