With the greatest of respect t’s really none of your business to try to persued her either way. You also need to be carefull you don’t give her a complex about the tattoo. If someone is telling you constantly that something is wrong with your body it can have a serious effect in the persons confidence and create alsorts of problems, just like telling someone they are ugly or fat all the time.
Tattoos can represent our past, our life and the times we have, good and bad, and you without the tattoo will never understand if it does mean anything or nothing to her, it’s not like putting a poster above your bed. If people expect to always feel the same about something then they are rather naive. I’m sure the majority of people with tattoos wouldn’t have the exact same tattoos they have now after 20 years or whatever if they had a clean skin and were able to start again, that coz we change and our thoughts change with us, and modern methods change with artists capabilities as well as design, and to be honest the majority don’t realise this until we occasionally take stock of what we have and try to install old thoughts on our more modern life. It doesn’t work like that so…………..
This tattoo will be fine, if it is effecting her negatively then she will get it removed. She doen’t need you or anyone else to persued her how to change her body.
