Absolutely. Change can be hard to cope with if one doesn't like the change. Doesn't even need to be insecurity involved, but of course it can be. I would hate having a husband all of a sudden that wants to go out partying every Friday and Saturday evenings because I'm usually tired and only want to cuddle up at home.
And Billy Bob is obviously having some kind of tic right now that enforces hitting the "haha" button under several postings in a row, lol.
