<human>: Can you provide a brief rundown of the text in within 3 sentences?

Quick back story: I'm a geeky introvert and not always 100% comfortable socially with new people. Also a year ago I was overweight/borderline obese, but since then I've lost a lot of weight and am just on the upper edge of average for my height now. It's made me more confident, but I've still got some shyness to work out.

So, last night I was out on a first date with someone I met online. I had a hard time picking up any signals and wasn't getting a strong 'yes' or 'no' vibe. I was trying to convey as best I could that I was interested, without seeming...well, awkward like I felt. We were doing the whole "get to know you" dance, but whenever it got quiet things they seemed a little uncomfortable, so I would bring up whatever other topic came to mind, even if it was totally unrelated. 

For some reason, I thought it would be a great idea to talk about the site we used to find each other. I don't know why, I guess I was tired/anxious, but the words that came out of my mouth were: "How do you like the site?" "What do you think of (some feature)?" and then my favorite, "Do you think I should stick with it?"

Yep, I basically said, "I'm really not interested in you." 

I could see the surprise when I asked that, and immediately knew it was a stupid thing to say, but what could I do? It was too late. We hugged when the date was over and I got a text later saying they had a good time, but let's just say I don't expect to get another one.
<bot>: Had a hard time reading my date, got nervous, and basically said to their face I wasn't interested, even though I was.
