He's most likely trying to get a reaction from you, so he can complain about how controlling you are. Don't take the bait.
My W did the same passive-aggressive stuff with me after one of our blowouts. Unfriended me, deleted all my pictures and posts, then changed removed her marital status. For what it's worth, and for all of her bluster, she's still here.
Also, in another FWIW, back when things were good in my M, whenever I had to go out of town on business, my W would pick a fight with me right before I left. It always used to irritate me, until she confessed one night that she did it so she would be too mad to miss me when I was gone.
I didn't see in the thread; does he know about the trip? He may be worried that you are going to visit the "City of Love" without him. Let him sweat for a while...
