If your spouse publicly boasts about their successes, they may be flexing. "If your spouse is continually sending you texts bragging about stuff, it's a clue that they're bragging and utilizing texting to do so," Masini explains. "It's called flexing because it's using your fingers to type instead of your thumbs like normal people." Flexing can also mean that your partner is feeling insecure or inadequate and is trying to make themselves feel better by showing off their accomplishments to you. "If they're doing this regularly, it's a sign that there's some insecurity going on with them," Masini says. "They might not know how to handle it, so they just take out their feelings on you." Finally, if your spouse starts using texting to get back at you for something they did, then they may be flexing as well. "If they send you dozens of texts in one day then skip right over breakfast with you every morning, they're probably angry with you and aren't thinking clearly," Masini warns. Texting while driving is dangerous and can have devastating consequences for others. If you suspect that your spouse is flexing, call them immediately before getting into an argument via text message.
