If one doesn't have pictures with a "girl/boyfriend" ish on his/her social media...?

[?]

...like IG or facebook or whatever, does it mean he/she is single?

[Laura]

Not necessarily

[Finwie]

No, not necessarily. Some people just don't like to expose themselves that much on social media.

[Heisenberg]

No. As a rule I don't post couples photos on social media sites and I know a large number of likeminded people.

Perhaps the whole couples photo validation seeking behavior is more closely akin to the motivations of the younger demographic. Most adults seem to avoid that type of attention seeking behavior - well, most healthy and balanced adults.
