I'm so confused

hey guys! for the last, i'd say, 3 months? I've been talking to this girl. We met at college we have a class once a week and we've become quite close over time. I really like her! She's funny, so so super smart (like way smarter than me I actually feel stupid around her), she's quite quiet and keeps to herself which I like. Anyway, I feel we've become really close but we only saw each other once a week for a while.

Eventually, I got her socials and we text back and forth now and then. Sometimes we text for hours into the night, sometimes we just send a message to each other once a day when we're both busy with work or whatever...

Anyway, around a month ago I asked her out! We went and had dinner and it was brilliant went so well I could tell she had a really good time and she immediatly started planning our next outing. Only thing is, I don't know if it was actually a date.. y'know? We went, chatted, laughed but we didn't do anything really intimate I just ask if she wanted to go out I never used the word date...

We went on our next outing, it was good! Same deal tho, wasn't really a date we just saw some movies and walked around the mall. Wasn't good as before but it was still fun.

Then, that same week, we met at college. She seemed kinda distant and quiet and she didn't really say much. I was confused and I got really worried that day i'd done something wrong was driving me nuts. But, she texted me that night apologising for being quiet and that she was just tired and stressed- unprompted. Which made me feel alot better and i said she didn't have to act okay for me.

So, we planned our next outing- this time it was somewhere I wasn't used to or knew where anything was (her idea). It... didn't go great. I don't think it was my fault there was just a few too much wandering, not knowing what to say. There was a few things I wanted to do but at dinner she said she had a migraine so i offered to take her home early just cause I didn't want to drag her around if she wasn't feeling well...

I texted her the following night, sorry things didn't go great and hoped she felt better- she told me not to worry and she had a good time still so I felt it was still okay! We haven't been out just us 2 since :\. We where gonna go the following week but all our course work due dates are coming up and we're both so stressed she said she'd rather wait 3 weeks from now until all the work is done for this semester. I don't think she is putting me off or trying to say she's intrested cause it's definatly not a lie since i'm feeling the pressure too right now but it's kinda sad I have to wait THAT long. She was taking espcially long to get back to me that week too (up to 4 days without a response was the longest).

This week was okay, we're texting again more frequently! On Monday we where texting wayy before we should of been in bed and that felt really good It made me think it wasn't over.

I finally saw her again yesterday, it was really nice to see her i nearly forgot how pretty she was in person. There was a bit of awkwardness, i was a little bit quiet...
I think it'd just been so long and I didn't know what to say (I'm not always great at holding / starting conversation, especially if im feeling the anxiety) :\
So i left early, just cause there was alot of people around- we weren't really alone it was a group. Plus i had work to do anyway.

We texted again that night, she seemed happy to text and had a fun convo but she did kinda just go off without saying anything whch kinda worried me.
That leads me to NOW! Honestly, I really really really like her I think she's amazing and I told her I didn't want to lose contact after we graduate and she said "of course!!!". There's still a little voice telling me shes just saying that but I hope not. What's my next step? Should I clarify my feelings better? Next time we go out, should I ask if it's a date? We've known each other for so long but we're taking it so so slow, if she even thinks we're getting close like that. I don't think she'd go out of her way to go out with me if she didn't feel something? I'm just really confused and want some honest advice. Since we're still in that weird end bit of rushing through college work, i imagine we'll just keep text contact for now until the 3 weeks are up and then we go out? What do you guys think i stress about this constantly. Thanks!
