A lot of people use social media as a way to keep "backburner" relationships alive. These could be exes, past dates, or even friends you felt a spark with, and you keep these people in your life in a semiromantic way with occasional messages, snaps, and shares. "This can harm a relationship because these backburner relationships ultimately draw your focus away from your current partner, and it's very convenient to emotionally cheat with them when your partner upsets you," David Bennett, counselor and relationship expert with Double Trust Dating, told POPSUGAR.
