<human>: Long story short, Back in middle school and high school I was made fun of for telling my crush at the time that I liked him (he was my first crush) by my whole class, also including him. Got over him, but in the back of my mind I was afraid to put myself out there again because of what happened before. After that, every guy I've had feelings for ended up asking me if I liked them, and well, to say the least the friendship would always be lost. Until I turned 18. I had my first boyfriend (I gave him everything, first kiss, first everything...) and that ended with him cheating on me twice (one with some random girl online and the other with my ex-best friend, they had a relationship while we were dating, it didn't end well). Now there's this new guy I like, I think he likes me back (but wouldn't know) and I'm afraid to start liking him because of my previous luck with other guys. Am I just being paranoid for holding on the past or what should I do? Some advice would be really appreciated.

Can you summarize the given text in a few sentences?
