Facebook have introduced a button which lets you ask about a user’s relationship status.
On someone’s About section, there is now a clickable “Ask” button next to their relationship status.
If clicked, it brings up a box that says “Let … know why you’re asking for her relationship status”, and the option to include a note.
The feature has apparently been rolled out to users since January, and also appears next to career, hometown and phone number information.
If someone requests your relationship status, you can reply using a drop down box of statuses like Single, In a relationship, Engaged, Married etc.
You can then choose to share it with the person who requested the information, or make it public.
