1 I hope no one is seriously suggesting that it is not for the OP alone to decide what they do with their body.
@1Ta1T Yes when it comes to this superficial/trivial issue and most issues. Tattoos are very safe nowadays, she's unlikely to be taking a risk of disease by having one.
I don't know much about tattoos but I think I am right in saying they can be removed. If that is right, it seems to me to be wrong to argue, as some people here seem to be, that she almost had no choice but to have a tattoo of her second child's name bearing in mind she had a tattoo of her first child's name: she had a choice between removing the first child tattoo and adding a second child tattoo and she chose to do the latter.
Most people wouldn't remove a name of their child. The symbolism of that would just seem wrong. The older child could well be old enough to realise she's done it, too.
The results of removal can be unimpressive with it just leaving a ghost/visible outline of what the tattoo was behind, and it's a long and expensive process, more so than writing the word.
just as it is the OP's right to do what they want with their body, it is her partner's right to decide what person he spends his life with
Yes, this writing of one word would be a pretty daft reason to split with someone though (unless someone were using it as an excuse.) Maybe if someone eventually got tattoos over a massive portion of their body that they didn't before.
So the OP chose to have a tattoo they did not need to have
You feel she doesn't have to have it. She feels she should have it.
they knew it would make their partner at the very least temporarily unhappy
There's being inwardly unhappy and there's casting a cloud over the house by how they demonstrate it. Some men do that and it's really unpleasant.
