AIO this girl im talking to comes off as really dry and uninterested

Back story: I met her through a friend, we’ve been texting in DMs overtime and are due for a date next week.

So I’ve been talking to this girl for around 3 weeks now and to me she comes off as really dry for example I ask what did you do today? and she’ll respond with not much or gone out with a friend and then that’s it so then I have to keep carrying the conversation and it is exhausting cause it’s like there’s no contribution whatsoever. We max out at texting each other maybe 5x a day. She never really wants to call over the phone maybe once a week, I’ve been asking to see more pics of her but i only get one once a week hahah and she deletes it straight away. She has told me she’s into me and into my personality etc but it’s like im not getting the same amount of energy that I give out.

I’ve never really dated or liked someone like this before and I honestly don’t know what to think. It’s almost like I want to trust her and do trust her but it’s like my brain (not heart) is sending me other signals.
