<human>: Can you summarize the given text in a few sentences?

I'm a senior in college and met a girl in one of my computer engineering classes. One night we were the last two people in the computer lab while compiling a programming project. We started chatting and flirting and by the end of the night, exchanged numbers.

I took her out for bubble tea, coffee, and other things as we got to know each other a bit better.

A few nights after we first met, she came over and we had our first kiss. That night, she did say she wasn't into monogamy ("Then you only get one.")

Even so, we started seeing each other more and getting closer. Two weeks after meeting each other, we had sex and cuddled. She started sharing more with me about her family and life, while she's typically pretty reserved about that stuff.

Last night, she came over and in late night talking, I asked her if she had any interest in being exclusive. She said no. And I asked if since we started messing around, if she messed around with any other guys. She said there was one other guy.

I'm conflicted in that I like her and I care about her; but don't want to continue what we're doing if someone else is doing the exact same thing. I don't hold anything against her because we never stated we're exclusive and she said she's not looking to date. I personally don't want to be messing around with multiple girls at once, so would like to be exclusive. But she doesn't feel the same way.
<bot>: A girl I've been seeing for a month or so told me she's been messing around with another guy. We aren't explicitly exclusive though.
