never do that. not sure what the karma and bad voodoo say about this but quite sure, not good. Get a necklace with his name. rip the thing off when he dumps you or the other way around. move on. no visible scars. there ya go.
Hmm. This reminds me of the movie "For Lovers Only", if you've ever seen it. A man and a woman who used to be in a relationship meet up years later and have an affair. In the movie, it is revealed that the man used to have the woman's name tattooed on his arm, but had it turned into a wolf. The woman then tattooed the name of her current spouse on her thigh.
I think the idea of it is appealing, but as I have no other tattoos, I'm not sure I would go through with it. It seems like more of a safe bet to get a tattoo of your husband/wife's name rather than a boyfriend/girlfriend.
