<human>: Can you succinctly summarize the text in 1-3 sentences?

So, last week I met this guy who came into my office to wait for a friend. We ended up having a lot of things in common and talked for quite awhile. I could tell he was interested, but I was not. Before he left, he asked what I was doing when I got off work. I didn't lie - I told him I had another commitment which happened to be a fundraiser dinner I was hosting that night. I told him he was more than welcome to come to that - as we were trying to get the word out to as many people as possible.

I realized after the fact that it was a really stupid thing for me to do. He wasn't able to come to the dinner, but texted me later to say why. I said it was okay, and assumed that was the end of it.

He texted me the next day, and then the day after that. I got freaked out and didn't respond until a few days later. I'm not interested in dating him - though he is nice and I think he would make a good friend. I also have feelings for someone else, which puts even more of a hamper on it. 

I finally texted him back yesterday, just saying "Hi, how's it going?". Today at work, he called me to ask what I was doing tomorrow after work.

I don't know what to do anymore. I don't want to be rude, but I'm just not interested in going out on any kind of date with him, and I feel like that's what he's getting at. 

Help me, Reddit.
<bot>: Met a guy. He's interested, I'm not. He keeps asking me to do things. I don't know how to respond without being rude.
