at one point in development, Jarl Elisif was a potential marriage partner but 'Thesda eventually removed that option... at least on Xbox and PS3. of course, nearly every NPC you help with their 'issue', they'll say that. to my knowledge, it's primarily the female NPCs that say it. i think a few males say it too but they're few and far between (that or i hardly pay attention to NPC chatter in cities, towns and camps).
I don't entirely believe that she was cut as a marriage option as there's parts of a cut quest to kill her still left hidden in the game, and Corri English voices Elisif and for example Ysolda who can be married so the voice type has marriage dialog for the other npc's that can be married (but it is possible).
Male characters usually say "you've been a good friend to me" instead. Like i said it means they like you the average npc starts of indifferent to you doing something they don't like (like killing a relative) will reduce their disposition, but doing them a favor will raise it. Their dialog will change (each voice has a different line) along with their disposition.
If a npc is marriageable those lines will usually mean they will respond to the amulet, but otherwise it just means you might be able to take some of the items from their home without them minding (the stealing tag will be removed) and vary rarely they may give you a gift.

no you could marry her but was scraped as that would mean LDB could be the high king which meant setting a canonical race gender ect.
That's just the standard greeting characters with that voice actor give you when they're your friends. It can be said by marriageable characters (such as Ysolda or Camilla Valerius), but also by multiple non-marraigeable characters (such as Elisef, Ingun Black-Briar, and Fastred).
I was going to her for the quest to put that war horn at a shrine of talos, and she said "its a fine day with you around", I put on my amulet of Mara only to be disappointed when I didn't see the option for marriage T-T
