Break-up Gone Bad

[this is amber]

At first it started out about a party at his house, everyone was invited included this girl friend of mine..which i had no problem with in my dream, everyone was having a good time and was getting along until i left the room and came back to his arm around her from behind and was kissing her cheek. Instantly it turned into a fight, then we broke up, then it turned into me completely balling my eyes out and being ridiculed by an unknown friend of his...right before his unknown friend started bashing my car and pouring paint on it and spraying me with a hose until i ran out of reach. (...something like that would NEVER happen in real life.) ...but the thing that bothered me the most about this nightmare was that through the entire fight he didn't care, whatsoever...i woke up feeling stupid and used.

Question:
What's my problem? haha.
