Best Break - Off letter

A soldier stationed in Afghanistan recently received a letter from his girlfriend back home. It read as follows:

Dear Ricky,

I can no longer continue our relationship. The distance between us is just too great. I must admit that I have cheated on you twice, since you've been gone, and it's not fair to either of us.

I'm sorry.

Please return the picture of me that I sent to you.

Love, Becky....... .......
