Folks can't help what their names are when they're born. I personally would struggle dating someone with the same name as my Parents due to *Trauma especially associated to one of the names, but folks can't really help what name they're born with. I feel bad when I react to hearing the name of my parents on other people, I can't handle it, and I opt for Nicknames if they are a friend or someone close for my own sake.
BUT, Umbreon needs to talk with their Significant other and not some random weird internet stranger if this is about your own personal relationship. Internet strangers are not relationship Gurus, and everyone's own relationship dynamics and needs are very different between each other.
