She is starting to fade away, realizing that you are ahead of her emotionally.

When you asked her to be your girlfriend after three dates, she was taken by surprise, and has had to go through a mental realignment since then.

She isn’t used to getting into exclusive relationships with guys after only three dates.

A lifetime of dating has taught her that more time is required for her to get to know you better.

Only then is she equipped with the information that is required for her to determine whether you are trustworthy.

Someone trustworthy is someone that has made her comfortable enough to let her guard down.

As far as she is concerned, three dates isn’t enough for that.

It’s too soon for her.

This is an unfortunate example of someone putting the cart before the horse.

The fact that she went out on three dates with you means that she was connecting with you.

She liked how the dates went and was looking forward to getting to know more about you.

By asking her to be your girlfriend after three dates, you created undue pressure.

Until that moment, she believed that you were courting her the right way.

Once you asked her to be your girlfriend, that bubble burst.

She was no longer in this easygoing and naturally progressing courtship with you.

Rather, it felt as though the courtship had acquired a set of tires and was barreling down a highway.

The courtship had switched from gradual and safe, to fast and haphazard.

Since then, she hasn’t looked at you in quite the same manner as she once did.

Any butterflies you had made her feel have now been replaced with unease.

She has talked to her friends about what you said and they weren’t supportive of it.

Girls listen to their female friends.

Undoubtedly, they have told her that this was a desperate move by you and that you are trying too hard to lock her down.

Not only has she felt a personal unease about your request, but her friends have made her feel that much more uncomfortable with the fact that you asked her to be your girlfriend after only three dates.

She is fading away as she opens herself up to new offers from other guys who want to take her out on dates.

Until recently, she wasn’t all that receptive to their offers, considering that you have been courting her, and she wanted to give your efforts her full attention.

Now that you have made it known that you want her to be your girlfriend, her mindset has changed.

She is entertaining offers from other guys who want to take her out on dates.

For now, she wants to go out on a few dates with those she deems worthy, to see whether there is a romantic connection.

Once she determines there is, with one or more of them, her fade away segues into a complete shutout.

She won’t bother returning your texts or phone calls anymore.

She moves on to the next guy.
