One more thing to add, I notice you mentioning he does not care and that he took you out of his life with ease. This is soooooo not true, its just what it appears to be in your view. Example, I was chasing an ex not so long ago and I decided it would be best for me to go cold turkey on her A$$. Knowing her she thought that it meant I couldn't care less about talking to her and that if I really cared I would feel the need to speak to her. In reality I cared a great deal, I just didn't show it, I didn't call, message, wish her happy b-day, nothing over nothing. It would appear I was over her, I was not even close, I thought about her everyday, fought myself to not call, I missed her, hoped we'd get back together, but never called. To this day she still probably thinks I pay her no mind, again its not true.
What WE think and what is actually happening may be entirely different.
