11 Social Media Habits That Could Mean Your Partner's Cheating

If your partner has a separate Instagram account — one where they never post about you — or another Facebook page that they use primarily for talking to friends you've never met, that's a red flag.
As Lavelle says, "When social media accounts change or the postings start to change, it can be a big clue that your significant other could be cheating."
While there are plenty of other explanations for a second account, or a joke posted on a ex's wall, if you have that gut feeling that something's going on, do bring it to your partner's attention.
You don't have to go looking for these problems, or be hyper vigilant for signs of change, but you can follow up if something seems out of the ordinary. By having a conversation about your relationship, you may be able to nip cheating in the bud before it happens. Or, at the very least, get to the bottom of why they're being unfaithful, so you can start to mend your relationship — or move on.
