After a long relationship Blitz broke up with Dash because she was getting 'boring'. Dash was very upset and depressed about this, she tried killing herself so many times but she just couldn't do it. After a while the depression passed and she just felt alone, she had no one to hold her and tell her she's not alone.
One day Rainbow Dash went to go see Twilight for some odd reason, she was walking over when she bumped into a stallion wearing something hard and metal like. She was greeted by none other than Prince Dusk Shine.
"Woah!!"
"Are you okay?"
"Yeah I'm fine."
"I don't think that we have formally met, I'm Prince Dusk Shine but you can call me Dusk for short."
"I'm Rainbow Dash, you can call me Dash for short."
He was so cute all dressed up in his royal attire, he was just so kind to me I didn't know what to say so we stood there in silence.
"Well I need to go see Princess Twilight but I look forward to talking to you soon!"
"Yeah."
Rainbow Dash had just found her Knight in Shining Armor, or Prince at least.
