So do these screenshots mean that you must never text your ex? Of course not. If your split was civil and a few casual exchanges don't set either of you back emotionally, it's all good. As with most situations concerning relationships, you have to feel it out.

"You shouldn't wait too long after a breakup to text your ex if things ended cordially," relationship coach Chris Armstrong told Elite Daily. "That creates awkwardness," he explains. "Instead, it's best to build a nice and immediate bridge between the relationship and a friendship."

But that doesn't mean you should bombard them with texts, revealing all of your emotions, either. Give yourself and your former partner a bit of time and space to process everything and come to terms with the end of your romantic before starting a healthy friendship. 

Keeping in touch is a bad idea if one person wants to be friends while the other is still heartbroken about the relationship and is unsure of how they see the future between them. Say your ex still tries to reminisce with you about the good times you shared together or hints at the idea of you two reuniting later on in life. That means they're probably not over the breakup. If you have already moved on, however, further chatting might just hurt them. The best course of action in such a scenario would probably be to give them space.

Either way, there is no formula for every situation out there, so you might often have to rely on your best judgment. That being said, be careful when it comes to texting your ex early in the morning or late at night. At least Chris Armstrong advises against it.

"We all know what communication in the morning and evenings means between two people who have or have had, an intimate relationship. It means good morning and goodnight in a not-so-subtle way, and you don't want to get those signals crossed with an ex."
