To someone:

I don't understand why you are treating me this way. We used to be able to laugh and joke around... I don't know what caused you to suddenly change your mind about me and just ignore me for reasons i know not. Have i offended you? Have i done something wrong that has caused your inconvenience? I would like our relationship to return to the way it was... Your coldness leaves me upset and confused... if only you could tell me why... It's uncomfortable being left out by one person, and now by you too...
