<human>: So I asked this girl out after class today just to hang out and have lunch. At first she hesitated say she was a busy person then when I asked for her number she told me she had a boyfriend. I am very certain she is telling the truth here and not getting rid of me. However I still did get her number kind of awkwardly at the end. I need to text her something what should I say? Like hey sorry I didn't know you had a boyfriend. How should I go about this? I'd like to remain on a good footing with her in case something happens down the road. How can I make this into something positive?
*I see her daily in class

Give me a shortened version of the text
<bot>: Asked a girl out. She has a boyfriend but I still got her number. What should I text her to keep things between us good/ not awkward?
