<human>: I'm an almost 25 yr old lady, he's a guy who just turned 23. He is a co-worker at my new job of 2 months. 

We started chatting just office casual, and we have some common interests, and he is incredibly sweet and gentlemanly (something hard to come by). We were having such a nice email convo at work that I wanted it to continue, so I told him just to text me. I was very well meaning, and I totally meant it in a friend way, (I consider myself "one of the guys" and I didn't think about it from his POV) but, understandably, he took it as something else. So, once I realized my mistake, I apologized profusely, made it clear to him I thought we would make good friends, and left it at that. He was a good sport about it.

However, we've still been talking a lot, and I really really enjoy our conversations, and I am slowly finding myself becoming "mentally attracted" to this guy. My issue is that I'm not attracted to him physically. He's too young for me in my opinion, and visually, he just doesn't do it for me. 

I feel like a very shallow and small person for admitting this, but it's a new and very real predicament I find myself in, and the last thing I want to do is be a horrible person and lead him on. As much as I'm growing to like him, sadly, I just don't see a future for us dating. I just don't know how to handle this situation at all...

Can you give me a shortened version of the text?
