I have experienced one kind of rejection that was rather open and understandable
Anyway, It all started in 2011 about September when I met a girl in a soiree my school had with them. After talking a lot we got close to each other and dated for a couple of months. However, I started to realize that our relationship wasn't working, so in December we broke up, both of us agreeing on both sides.
Then in February 2012, I decided to talk to her again and wondered if we would like to start over. However, she rejected it and told me that she had already found another love in her life, another girl!
. She explained to me that she discovered that she was a lesbian and I understood what she felt, so we parted ways after that. However, I never had a heavy feeling for what had happened because I understood what she was going through, we agreed to stay friends and until now we still keep contact with each other.
) for everyone who decided to share something with us 
It's sort of my theme song for a couple of people who betrayed me as friends, and if they ever thought they could be my friend again, I'd play this song to them.
