<human>: I [17m] asked a girl [17f] I have been dating for two weeks to be my girlfriend. She said she didn't want a boyfriend.

I took that to mean we weren't exclusive, but she just texted me saying she's been crying, and she doesn't want to lose me.

Since I last saw her, I have been on another date that she doesn't know about, on which I think the girl [17f] wanted me to kiss her. I managed to stop myself because I felt guilty, but I'm very attracted to them both, more strongly to the second girl, and I feel like an asshole and a cheater. 

I feel as though the 2nd girl and I have a stronger connection, but the first girl has opened up to me emotionally and I feel like I'm betraying her.

What should I do? Sorry if this is the wrong subreddit!

Give me a shortened version of the text
<bot>: This is the first time in my life that any girls have shown interest in me, I have no idea what to do.
