Yes, I have a few of those as well. I used to keep the sweet ones where he called me baby and sweetie and said how much he loved me. But, those got replaced with the
ones where he tells me to go have a nice life and to go f myself. Or how I was full of S*** and I needed to call him NOW at 3 a.m.
The difference is night and day. I kept the bad ones to listen to when I had any thoughts of going back to him. It helped a time or two but I seem to disregard them when we are back together again.
