<human>: Can you provide a brief rundown of the text in within 3 sentences?

i really, really like this girl, she's one of my best friends, and from some advice I've gotten, i think she might like me too.  I don't know how much, or if she actually does, but i am starting to think that she does.  Where it gets weird is that she's given me advice on how to get into a relationship with her best friend.  That ended badly.  A few days ago, she invited me and another of her guy friends to exchange Christmas presents and watch a movie at her house.  She loved what i got her, and i think it made a good impression.  During the movie, she kept leaning into me, and there was contact of legs, shoulders, arms, hips, throughout the whole movie. yes, it was a scary movie, but most of the time we were laughing and talking and looking at each other, so I don't think the fear was a huge factor in it.  Our friend had to leave early, but i stayed behind for some company.  We talked and hung out for about 20-30 minutes and just had a lot of fun.  As i was leaving, she gave me A longer than usual hug, and said "Thank you (insert name here)" and I had been noticing her looking up at the ceiling a few times.  Right before i left, i looked up at what she was looking at, and it turns out it was a mistletoe.  At this point, I was already out the door and walking to my car.  Later that night, I was texting a mutual female friend of ours, and when i explained the situation, she responded with "I never miss an opportunity to miss an opportunity" is this true?  Reddit, do you think i should've gone for it?  Did i have a chance?
<bot>: i really like a girl, we hung out, friend says i should've made a move based off of what happened.  Do you think i should have?
