<human>: Saw a cute girl in one of my classes and sat by her. She gave me her number and asked to study together.She is really cool and we got along great. After one month of studying together often, phoning, texting and no mention of a bf (after giving obvious chances) I asked her out. The convo went like this.

Me: "hey what is your schedule like for the beginning of the the holidays?"

Her: "nothing planned why what's up?"

Me: "I was just wondering if you would like to go out to lunch?"

Her: "like a date?"

Me: "yeah If you aren't seeing anyone"

Her: "Im sorry I have a boyfriend"

Me: "ok I didn't pick up on that haha sorry"

Her: " I guess I don't talk about him a lot. Sorry I didn't mention him, if I wasn't with him I would totally say yes"

Then I changed the subject to a recent test we had in school. She texted me after and said that she "really appreciates our studying and she hopes that we can still do that" and I replied of course nonchalantly. Also she revealed that she is older than she looks, she is 25. Now that dating is out of the question how do you transition back to the way it was before. I don't really feel awkward because she was so cool about it and that it turns out she is quite a bit older than me. But how can I reduce awkwardness as we are in a bunch of classes together next semester and I really do like studying with her. My plan is just too treat her the same way I did before I asked her out. Advice? Has anyone else ever been in this situation?

Can you condense the text into three sentences or less?
<bot>: asked out a girl she had a bf. How do I act to make the situation not awkward. Still want to study with her and we have some classes together next semester.
