<human>: Can you give me a shortened version of the text?

Hello r/relationships. I was hoping you guys could offer some perspective on this issue that my husband and I are having. A quick background, my husband and I were best friends for a while before we dated and therefore told each other things that we may not have if we had known we'd be together. We've been married a little over a year and he is simply the best man I have ever met. We love each other very much but.. this issue seems to continue to pop up. Mostly because I can't get over it.
 
When he was 18-ish, he fell in love and got a tattoo for his girlfriend at the time. It's not a matching tattoo or a name or anything but he got it for her (and told me about it). He has many tattoos and he's told me more than once that he regrets getting some of them as they do not represent him anymore. However, this specific tattoo he does not regret. He says that although at first it was for his ex, now it is just a cool piece of art to him.
 
He's mentioned covering up some of his tattoos to be something different and I've asked if him if he would change the ex's tattoo and he said no. Now, a part of me says that he was a dumb 18 year old and that tattoo doesn't really matter anymore but the other part of me is hurt that he would want to change his other tattoos but not this specific one. 

We can't seem to agree on a resolution and I don't want to force him to do anything he doesn't want to. We would both like some perspective on this from someone other than each other (He knows that I'm posting this to reddit so feel free to direct comments to him too.)

Am i just being a brat for not letting this go?
<bot>: Husband got a tattoo for an ex and doesn't want to cover it up because it's art to him now, but wants to cover up other tattoos that no longer apply to him.
