Maly, who knows on the tattoos. Maybe it's a way to rebel. My W had two tattoos from college and about 3 weeks after the BD she got two more. Did your W have tattoos already? Could be her trying to get back to her "self" at some other point in her life.
I will say that I got a couple tattoos in July and it's somewhat addicting for some reason. Already trying to figure out what the next one will be. I imagine that addictive feeling has to be magnified 50 fold in our impulsive Ws right now so maybe that's why she keeps getting them. Just a thought, though sandi probably has a much better answer than I!
