I agree with OT but still, it has to hurt. Having him back for awhile and then he bolts again. Wtf. Rest assured that your boundary was perfectly reasonable. It isn't like you said she had to be barred from entering his workplace. That would be nutty as it is a public place. But he chooses his FB friends, that is totally within his control and should be understandable given the history.
I mean, what kind of 'friendship' does he think they can have? Like, "Hey me and my 'friend' are going to grab a beer after work Mish"..."Me and my 'friend' are going to go to a concert", etc etc. He can have plenty of friends, just not HER. If he doesn't get that, well, I just don't believe he doesn't get that. He knows it is right he just doesn't like having 'limitations' put on him. Tough.
