It's not just the relationship you left behind that takes time. If you don't wait long enough before dating again, you'll probably be doing yourself a massive disservice.
"A lot of people, the minute they break up with someone they are back out online again," said Erika Ettin, a dating coach and founder of dating site A Little Nudge. "That's not something I would recommend, because you haven't given it any time to sink in."
If you jump back into the dating scene too soon, you haven't given yourself a chance to learn from the experience, or mourn the end of your relationship.
"You're not mourning a person's life, but you're mourning part of your own life that is now not there," Ettin said. "Too few people take that time to actually get back to the equilibrium of who they are, to heal, or to figure out what they have to offer again, or what they like to do on their own."
So take a deep breath and allow yourself to take that time. People will always be looking to date, so you're not missing out on anyone if you don't re-download Hinge the next day.
