<human>: Can you give me a shortened version of the text?

I'm in a good relationship, but I was buying running shoes today and this cute girl who worked there helped me out. We were just talking, we had a really good connection, and I could kind of tell she was interested -- she kept the conversation going and we talked a lot, she even wrote her full name down without me asking for it "just in case you need to contact me" (I'm guessing so I could look her up on Facebook or contact her at the store). This girl was really cute, but like I said I'm not going to ask her out because I have a girlfriend.

As a guy (and maybe it's just me I don't know), I always hate it when I have a really good connection like that and then nothing comes of it. It makes me wonder if I did/said something wrong, or if I should have been more forward/make more of a move, etc. So not wanting that for this girl, I called her back at the store and just said "Hey, I think you're super cute and I totally would have asked you out if I wasn't dating someone. I'm sorry, I'm not sure how you were feeling, but I just wanted to let you know. I always hate having a really good connection with someone and then being unsure of why nothing ever came of it." She said she was flattered and thank you, and that basically yeah she would have gone out for a date with me but she understands.

I've never really done something like that before, and I don't know if it was awkward to do that. I was just kind of going by the Golden Rule here, thinking I'd want to know if I were in her position. **Girls of Reddit, is that something bad to do, is there a better way to do it, etc.?** As a generally talkative/conversational guy, I sometimes run into this problem with girls and I just don't know how to handle it. **Would it be better just to ignore it and not worry about it (just never see the girl again)?
<bot>: What do I do after meeting a girl and she obviously likes me, but I am in a relationship? Nothing? Tell her it's not her, just I'm not single? Thanks for any help!
