Hello Ex-Headache

Dear Ex-Headache,
Life has not been the same since that day when I first laid eyes on you. I have been through numerous changes and so has my family dynamic. We were not meant to be and that is for the best. 

You were by far the biggest headache I have ever experienced in what was loosely called a relationship. I knew better than to stick around. The tantrums, name calling when you could not do something for yourself and I refused to do it for you. The inability to take care of yourself, calling yourself grown yet being unable to pay the smallest of bills.

Actually I have far less to say to you than you would think. I am glad you're no longer in my life. I am happier knowing that I will never see you again.

Sincerely,
Someone who doesn't care
