<human>: Condense the text into a few key points

So, I recently met a girl online, we'll call her K. She lives in the same town as me, and we had been talking a bit online and texting when we decided to go out for coffee. The coffee (first) date was yesterday (Sunday), and it was a good time. It wasn't anything that made me think "hell no," but it also wasn't anything that made me think "this girl's great!" I went ahead and asked her if she wanted to see a movie later this week. 

Now, on Friday, I ended up going to one of my friend's wedding, and met another girl, call her S. Her date bailed right after the wedding, but she stayed for the reception anyway. We sat next to each other, and ended up dancing and having a good time. A bunch of us went out to a bar afterwards where she asked me if I was going to come to her place for a bonfire on Saturday. Based on the conversations we had at both the wedding and her place the next day, we seem to have quite a bit in common. I didn't want to ask her out Saturday, since I had been talking to K, and I knew I had a date with her the next day. I feel weird trying to talk to both of these girls at the same time. Also, it's worth mentioning S is living in my hometown which is currently 2 hours away.

I'm wondering what the norm is for dating/talking to two or more people at the same time. Is it okay? If I decide I want to be exclusive with one, how do I tell the other? Do I say it's because I met somebody else? Is it feasible to date somebody that lives two hours?
<bot>: Met two girls recently. Just starting to date one. Is it okay to date both? When do I need to make a decision, and how do I inform the other when I do?
