IMHO

Just a tiny correction: ЛЮБИМАЯ doesn't mean mistress, girlfriend, sweetheart or lover. It's an adjective and commonly must be followed by a noun that is described as "beloved" or "favorite".

For example, the word can't be used in the following construction when you want to say: She is my lover (or girlfriend, mistress, sweetheart)

Although in old 19 century poems written in high style this adjective was applied to a women to mean "woman I'm in love with"- this is not how this word is used in contemporary Russian language.

Exact meaning of word ЛЮБИМАЯ is "beloved one" and "favorite" (most common usage) applied to a feminine noun and unfortunately you can't use it alone, by itself - as it requires a noun to go after it. For example, it's okay to say ЛЮБИМАЯ ЕДА - favorite food. But if you say just ЛЮБИМАЯ - people will stare at you waiting for the next word to be spoken.

But - this word/domain name can be used for dating site or related service as it can be made into a trademark because the word does hold romantic connotations.
