I(17/m ) had my joy vanish for the girl(17/f) of my dreams in a month and I feel like a horrible person, what should I do?

I don't really know what else to say, we started talking February 26th and up until about a week ago I was having the best time of my life, going on a few dates, talking every day, playing games together.

but then about 5 days ago, I was scrolling through my phone and I saw a photo of her I had saved. and just like that, I felt my stomach drop. those feelings of joy were just gone.

she asked me why I had been so distant and not texting as much and honestly I didn't know the answer so I told her what I thought was happening, that I thought I was scared, that I thought maybe we were going to fast.

fast forward to the last day of March and it just all started spiraling, she says she can't be with someone who doesn't know what they want (which I understand).

and then yesterday, I went to my therapist to help get some answers that basically boiled down to " yeah that happens" and "did you like her, or did you like how she made you feel"

I've been texting her the past 2 days and the conclusion that she's come too is that she feels lead on, used, and confused.

I don't know what the fuck to do, I love her so much, it's only been a month but I love her, just the amount of joy I get for her company isn't as much as it was a week ago

as of a few hours ago we decided to pull back and be friends and see where that goes, see if I can get those feelings back. but I'm just scared, I can already feel the resentment.
