<human>: Provide a brief overview of the text.

This week I went to go visit a friend of mine who lives out of town. I had never been to her house before, so I didn't know anyone that was close to her aside from her parents and siblings. 
Well tonight, she decided to have a party. I went, and I was having a really great time meeting new people and hanging out with them, when a cute guy about my age came up to me and introduced himself. We eventually split away from the group and ended up talking and laughing for a couple of hours. We clicked and he seemed like a really nice guy, so when he leaned in to kiss me I didn't stop him. 
Later, near the end of the party, he and I met up with my friend who had been busy all night. She looked at the both of us and smiled, and I assumed that was because she knew I found a guy I really liked. 
But then, he walked over to her, she slipped her arm around him, and she said "Oh hey, looks like you met my boyfriend!" 
He just looked at me with zero remorse and I stood frozen there for a few seconds before blurting out some excuse and leaving. Not really sure what to do now.
