Social Media Death of Relationships?

I read a lot of stories on this app about relationship drama regarding social media (Example: my boyfriend added her on instagram, caught my boyfriend snap chatting an ex, etc). Can I just say, neither my husband or myself have any type of social media (no Facebook, instagram, Snapchat) and we have absolutely no one interfering in our marriage whatsoever. We have no drama at all and we are so happy and never talk about getting any type of it back (I deleted mine before I got married 3 years ago, he never really had any). Could social media be the death of relationships? What do you guys think? Do you think if you and your SO did not have social media you would be less worried?
