You know Chicki I have done similar things and I although I have no idea what is going on with my H and his thing. I will say this. I should not have said anything becasue it was already on the decline.
Now I am stuck here wondering. But you know what, I have faith he will come to his senses and remember what we have. So I no longer say anything. He doesn't really live here anymore although all his clothes are here with the exception of a few work items and some shoes. He sleeps elsewhere. He told me he would "float." I am going to keep DBing to see where it gets me.
Next time you have an urge to send something like that. Just type it out and hit delete.
You don't think he could have been logged on then walked away from his computer for awhile?
