You may feel ridiculous for resuming relations with someone you swore you’d never speak (or sleep) with again. Especially if you’ve disavowed them several times only to find yourself stalking their instagram late at night and firing off later-regretted texts about how much you miss them. Getting back with an ex isn’t a terribly uncommon experience. There’s even an official term for it in the scientific literature: relationship churning. Though more common among adolescents and younger adults, individuals of all ages are known to engage in the behavior, including married couples.
