Oh yes as to FB, I think it is important to keep an eye on that right now for my own safety if nothing else. You see, I recognize that he has the propensity to be violent and unpredictable especially towards me but he usually gives some indication of that on FB. So when I see that I can take steps to protect myself like changing the locks which I may have to do again since one of my keys is missing since his last visit. I just have to find a way to better deal with the idiocy of the posts and not take them so personally as you say. That mess has hurt me true and I do need to detach. Part of the reason why I write about it here is to keep a journal of sorts in case he does something, as well as to get out my feelings about the craziness. You see I have been gaslighted too many times by him to trust him right now. The same for the suicide concern.
As to FB today, for the record, we are back to manic-posting at an unusal time-library is closed in the a.m., 6 posts in under an hour, with an additional 3 comments that border on strange, not in his voice at all-like "I wish it were true, no religion or countries. Who wants peace? I do."-Lennon's Imagine. Overall depressive, and getting more dangerous to servicemen in a mass killing kind of way but I don't want to jump to conclusions as he has said nothing about that other than to state he hopes the guy I dated who is in the military will die or be captured while he is deployed to the ME, and I think this is where his anger for the military comes from.
Now to lift weights, run, do yoga, and play with my dogs for myself!
