Would telling someone that's single ''you can still adopt'' taken as an insult?

If they're single, have no luck in relationships and someone tells them ''you can still adopt'' is that actually an insult, esp if they're fertile but just missing a partner?

They always say adopt as if that was the first and only option left. I heard someone once telling that to some normal, fertile woman in her late 20's. It actually made her feel worse.
