Rejected my boss and got fired

has this ever happened to you? My boss tried to persue a relationship with me and I rejected him, respectfully I told him I just wasn't interested. What happened was we ended up being really good friends, I was in a relationship and didn't see him as anything else than a friend. His friends and my friends including my boyfriend would get together and hang out. Ontop of that he was training me and encouraging me to go further in that job. Well, I broke up with my boyfriend. Then he invited me to a theme park and we had fun but the whole time he was heavy like trying to get it across that he was interested. He tried to hold my hand, I pulled away. He tried to walk up close behind me and I moved over. That night ended with me telling him I wasn't interested in anything but friendship with him. Next day at work, everything was different. He would barely talk to me and ended up yelling at me and tried to blame me for some nonsense that wasn't my fault and FIRED me.
