Can I ask my fiance to not get a visible cringe quote tattoo?
Maybe. Do you not like tattoos?
I think that's a bad idea to get a tattoo of a quote.
While you might not like them, it is not good to judge others who get them. Your boyfriend might really like them and would be happy with that kind of tattoo.
Probs not but I can use the engagement to control him and keep him from getting it.
That won't go well, You shouldn't try to control others or look down at them because they don't do things like you do.
