I 23M need to tell her 23F my feelings I have toward her by the end of the semester, what’s the best way to make my self clear so there’s no room for confusion… need advice please!

So long story short, I 23M match with a girl 23F from university on bumble several months ago but the time expired and we never met.

Ironically, we end up in the same class this semester and even the same project group. I kind of got the sense that she was into me each time we’d meet by sending off those vibes. I sent her a text this evening and said ‘Hey, I meant to catch you after class today but Mrs. xxxxxxx wanted to talk to me. I remembered you were in my gym class and wondered if you’d like to hit a workout next week. I’m thinking Tuesday night at 730.’

She replies and says “Hey! So here’s the thing lol I really don’t know what I’m doing in the gym ? so I always go to the cycle studio and get my time in there, you should come!”

I reply and say “I’d be down for that! Really though, I’d take you through my routine if that would help.”

She says “I’ll let you know, I may have a meeting with my group in my Marketing Strategies class.”

I say ‘Okay sounds good!’

And she says ‘Have a nice weekend ☺️’

So the following Monday night I had class with her, and right after it got over, I went up to her and tapped her on the shoulder to say hey and just said, ‘hey! Just wanted to say that if the workout thing isn’t your thing, that’s totally cool and I understand.’

She said ‘well….I have a group meeting tomorrow night….sorrry!’ And she didn’t mention anything at all about meeting up again at her cycle bar. I tried to make a little conversation with her about her place she goes to and just tried to play it off cool.

No a couple days later, I wake up to a Facebook friend request out of the blue from her and just a few days later the rest of the semester ended and everyone had to go home for the coronavirus so we never got to have the chance.

Fast forward like two weeks and she texts me out of the blue this evening to ask how I’m doing. This was the first time she has ever done this. We’re both seniors so it’s unlikely we’ll see each other again, so I feel like she must be thinking about me…. we are working on a group project over Zoom in one of our classes so I don’t want to be creepy or make anything awkward, but once this semester and project is over in like 2 weeks I want to tell her how I feel. What’s the best way to do that to make myself clear?

TLDR; what’s the best way to make myself clear about my intentions so there’s no room to wonder?
