Relationship status on Instagram?

[Anonymous]

I'm new to Instagram and the guy I'm dating put this in his Instagram bio:
BD ❤🔐 (my initials are BD).

What does this mean?
Is this a common way of showing your relationship status on Instagram? Do a lot of people do this?
How do you show your relationship status on Instagram?

It'd just a harmless way to say you've got his heart. I don't know if it's common, but it's simple and rather straightforward, like a relationship status on facebook

I've never seen that before. That's sweet. :)
