End of a friendship?

I apologize in advance for this potentially being an extremely long post and for any typos!
------------------- 
This girl and I have been friends for 3 years now and throughout the friendship we have had our ups and downs like any friendship. We are completely different people. Literally, we are night and day but somehow we became and stayed friends for so long. 
Anywho, we went on our second "mini-vacation" to Orlando with her cousin as a much needed getaway before her cousin and I started college again. (Keep in mind that the two of them are single and I am not. My friend of 3 years recently got dumped by her boyfriend after them going back and forth for years.) Most of the trip was fine other than the night we went out to a college bar/club. When I go to clubs o never ever dance with guys unless they're apart of the group that I go with. I always politely say no thank you with a smile and just go about my business. Most of the (if not all) night I was being asked to dance and turned down the guys nicely. I talked to a few but went on with my night and every guy respected that. There were some instances where a guy would try to talk to me but I didn't even notice because I was too into the music and dancing by myself to notice the people around me so it came off as rude to my friends cousin. At one point in the night, a guy grabbed onto my arm to dance with him (which is a big NO in my book) and I said no no I'm okay. Thank you smiled and turned around. A song that I love was playing so I went back to dancing and smiling. My friend immediately wanted to move from the section as she felt embarrassed for the guy. The guy didn't seem to mind or care. After all I'm not the only girl in the place for him to dance with. So she became upset and it bothered me because it felt like most of the night she was worried about what I was doing/kept tabs on me saying no to guys. Also keep in mind that a guy that she tried to pursue that night basically turned her down and I could tell her ego / confidence was bruised a bit. Idk if it's because she's used to attention being on her or not when she's back home but the case was different where we were at. 
I say all of that to say that we ended up exchanging texts and it got pretty heated. She felt that during a conversation we had on the drive back home that I insulted her (I said that I'm not like her in regards to being extremely friendly with everyone especially guys (bc of my past) and don't add guys or give my number. It WAS wrong of me and I admitted that. I simply explained that I was so frustrated at that point because she made me feel a certain kind of way and didn't even try nor care to understand. It's been a week or so since then and neither of us has spoken. The text conversation got that bad! 
I realized that we are completely different people to the point where it just won't work but am saddened by that due to the fact that despite everything we did have a solid friendship or so I thought. She was basically one of the few friends that I have but don't think that a friendship where you both feel like you can't 100% be yourself because you know the other person is a certain way. 
Have any of you had to end a long friendship only to have one incident or a few things happen so you see that the friendship end because of it? What did you do to deal with the fallout of someone who you were extremely close to?
