Is she not interested or am I reading into this too much ?

So I've known this girl for a while now (friend of friends) but only met a couple of times at a party or similar, until 3 weeks ago when we met again at a party where we chatted for a bit and ended up kissing. I got her number and asked her out which we ended up going out on a date for a couple of drinks and food. I think the date went pretty well, no awkward silence, we spoke for quite a while about eachother what we like and dont. I didnt feel there was much flirting as I'm not very good at it.

After the date she messaged she had a nice time and i said so did i and said we should do it again. She replied " yes we can do something again if you fancy ", that sounds to me like she's was just being polite and waiting for me to stop messaging.

She doesn't message very often, maybe once a day and that makes me think she's not interested.
