I still don't know how flairs work here lol

Long story short, I dm'd this girl on IG (I got her IG from her fb dating bio iirc, didn't match her there)

Talk has been fun so far, we've been texting since yesterday, we have many things in common, she's physically cute and overall she seems like a fun person, but we haven't talked about deep stuff yet since I wanna save that for a date.

I slightly took the convo to our (school) schedules, and then made a subtle comment about going to eat somewhere, and she told me that she's busy this week, and nothing else, we're on the same college, different career but I assume she's on exams bc I had mine this week and next one as well. (She just told me she's at home rn, haven't opened the message yet)

I noticed she immediatly saw the going to eat comment, she left it on seen like 5 minutes and then she replied she's busy this week.

Maybe I'm thinking too hard on this (?), maybe it's not as complex as I see it, but the fact that she didn't immediatly say she's busy got me thinking, maybe she's not that interested yet? Maybe she took a screenshot, showed it to a friend and asked her what to do? Idk I'm just yapping at this point.

My question is what do I do from here? Do I keep ocassionally texting her about her day or funny stuff? Do I wait one week or so to propose a date again? If I text her would going to ever-so-slightly deeper topics be a good play?

If you've seen my posts here before, you already know I'm new at the practical side of things (previous girl just blocked me for some reason I won't spend time thinking about ¯_(ツ)_/¯)
