Need a help with a Sindarin (for paired tattoos)

[K1ko]

Hello everyone, hope you have i nice day!
Can i ask for some help?
I wanna make a paired tattoos with my girlfriend, so, are there any word or phrases on Sindarin which mean "soulmates" or something like that.

Or very cute and lovely phrases or words which would describe the maximum intimacy between people.

It's also can be some lore stuff as Aragorn and Arwen love confessions...

Thanks a lot!
<3

I've saved my best friend's number in my phone as Oialëa Meldë which means Eternal Friend/beloved in Quenya. I think this is the closest to soulmate I could find back then.
