<human>: I feel like this could also be posted in /r/nostupidquestions because I think the answer is obvious but I can't really think about it the right way.  

Alright so that was quite a while ago (in march) and there was a party that some people from our school organized, basically I was there and had my favorite shirt on and I got compliments because of it, she (let's call her L) made a compliment too, I basically was in the process of walking inside the room again because it got cold, so I just said thanks and ran into the room without even looking at her...  

It was stupid, but I didn't even really knew her name back then, so she was interested in me first, anyway later at the party I see her making out with someone on the couch (someone she never met) and I glimpse over for a sec because there was smoke everywhere and it was hard to see, she was looking at me in that moment too, I was like alright (I didn't know she liked me), it didn't make me jealous, I wanted to know of her after a friend told me that L liked me (probably) though.

Now we're having a good time, I'm kinda reluctant because she's the first girl I'm actually going out with (although not too often) so I haven't kissed her yet after THAT LONG.

Can you condense the text into three sentences or less?
<bot>: She made out with another guy before we started dating to make me jealous (it didn't, she got my attention later because a friend told me about her), is it really a big deal?
