Business Insider: 6 signs your relationship probably isn't exclusive, even if you think it is

Whether you’ve already committed to being exclusive or have yet to discuss it, if your partner is still active on dating sites and on dating apps, they are probably not in an exclusive relationship with you, according to Celia Schweyer, dating and relationship expert at DatingScout.com.

“Being keen and active on dating sites and apps – this doesn’t include just having a profile you were too lazy to deactivate or have forgotten the login details of – should be a telltale sign that you’re not in an exclusive relationship,” Schweyer told INSIDER.
