I'm so lonely all the time...at least it sounds that you have somebody, because you are saying that you are not used to sleeping alone....so, hopefully time will pass and he will come back and you won't sleep alone...but I don't have that luxery in my life...I've been alone most of my life....so sad...and I'm trying so hard and I'm still alone
Sorry...I'm not that helpful....but try to read something or think about good stuff....
good luck
