I guess I was not clear. I did not say that he is weird. I do not know that. What I meant to say is that he does not have rational reasons to murder you and the reasons you offered, your age and his lusting after young women, would have been a reason in Agatha Christie's times maybe but not now.

Everything else you have said about him also does not demonstrate any rational reason to want to murder you (if one can be rational about that) or any intent or motive. You know how in detective stories, several things need to be in place to suspect someone of murder and one of them is motive? What would be his motive? Why would he want to murder you?

That said, this is all about rational reasons. He might be an irrational man and then who knows. I certainly don't.
