<human>: Girl #1: She's been my best friend for years. We've hooked up a few times already but I've been having issues committing to her. I'm worried that, in the event of a break up, our friendship will be over. I'm also worried that not pursuing this relationship could damage our current friendship. We're really compatible and there is some attraction there, but I'm not sure dating her is the best thing for us, at least not now. At the same time I don't want to lose her in my life. I do feel like I owe her a definitive yes or no. 

Girl #2: We met a few months back when she was single. I was immediately attracted to her and she gave me her number without my asking. I ended up losing the number because, you know, I'm an idiot. We recently reunited but she is with a guy she previously dated. I was fine just being friends with her until she recently admitted to having feelings for me. Now I can't stop thinking about her. I also share feelings for her but as long as she has a boyfriend I'm going to keep my distance. 

Any advice would be greatly appreciated.

Can you condense the text into a few key points?
<bot>: My best friend has expressed interest, but I think dating could potentially ruin our friendship. Another girl has expressed interest and I'm really attracted to her but she has a boyfriend...
