And Even if you had it still would be difficult to tell the real thingUnless you have close access to them in real life, you can't determine if they're happily married or not. Lots of couples out there portraying heaven on social media when they actually live in hell.
Many couples of friends have this perfect social media but when you "live" or spend most of your time with them you realize that it is anything but roses and flowers.You see posts like this and then they file for divorce a week or two later.
Stop believing what you see on social media. People carefully curate it to portray them as they want to be seen by others not as they actually are.
Better yet, get rid of social media completely and live your life in the real world not online.
