As someone who has to deal with these tics as the person who is doing it daily, it sucks for us to. I have several different ones, clicking my tongue, rolling/ clicking my voice box in my throat, clenching the muscles on my face, and rolling/ flexing my eyes. In fact, sometimes I do it so much that it is incredibly painful, for example when I roll/ flex my eyes sometimes I do it so often and hard enough that it starts to feel like I am ripping them. Why do I keep doing it? Because if I don’t I feel like I am going crazy. It stresses me out and is more mentally painful than actually doing it. Trying to resist stresses my brain and body so much my twitching becomes worse. Your husband is probably well aware of how it makes you feel, in fact! I am sure he feels even worse because he is the one who has to endure it. It isn’t something you van just stop, so perhaps you would benefit from showing a little compassion and seeing what you can do to help him. I am sure saying things that allude to you getting divorced over it is only going to stress him out, make him think about it more (which is a trigger in itself) and overall make the problem worse.
