I sent my ex an email pretending to be my crush's girlfriend?!?

Hey. OK so I broke up with my sort of boyfriend last week. He wasn't a proper boyfriend just some guy who had a crush on me cos I went to his kissing cles to learn how to kiss. I had to go there cos I wanted to learn to kiss propely when I finally got my crush to date me btw. I think my crush likes me back but he has a gf:( I got my friend Alicia to dump my ex for me and ever since then he won't stop bothering me. He has my MSN email and keeps sending me emails of how he wants us to get back togther even thoughh we weren't dating as such. He is like a stalker. So I though I would set him up with my crush's gf Lucy. What does he see in her? Lucy is soo mean and makes everyone's lifes hell. She is always looking smug and thinks shes better then everyone else. Lucy is a loser and so is my sort of ex so they will be perfect togther. Then with Lucy out of the way I can date my crush!! My crush seems to like me back as shown when he got annoyed seeing me kiss my ex at a party. So I managed to get Lucy's email from her friend Mandy. I pretended to be her and sent him an email saying I (meaning Lucy) had a huge crush on him and I would love to take him to the movies then after we can go back to my house (meaning Lucy's house) and show him my underwear with the lace (she is such a slut so that sounds like her lol). Then I sent it. Do you think my plan will work?
