I am so very sorry about your beloved cat. (hugs)
I guess you really have to ask yourself, in the months you have been apart and not talking – how much love or concern did he show towards the cat? I mean if the cat meant something to him he would have made an effort to spend time with it.
The mistake we make is in thinking that they think and feel like we do. You would of wanted to know so you could have said good bye had this been reversed but they are not like us, don’t think like us or feel like us.
Sadly and un-intentionally you have opened the door again – now you must close it and lock it for good!!!
Block his # and be done with him – AGAIN.
