Cute freshman girl I like...

the interest is gone. If she truly wanted to hang out with you, then she would put forth more effort. I would respond with "thanks, you too" and then ignore her

I think you're coming on a bit strong to be honest.

Instead of texting her ring her and see if she wants to meet up for coffee or something (just the two of you)

You've put yourself out there, maybe a bit too much but whatever, let her come to you now.
