It's embarrassing to mention publicly, but after a particularly upsetting breakup, I became obsessed with the idea that the relationship wasn't over because he hadn't unfriended me on Facebook. It didn't matter that he had said, "We're done." and unceremoniously walked out of my life for good. 

Since we were still "friends" online, I nursed the fantasy that there was still hope for our relationship. I clung to this delusion for months, checking daily to see if he had deleted me. Each time I saw that we were still "friends," I felt that his return was still possible and likely. That is, until the day when I saw that he had finally unfriended me for good.

I remember that day better than the day we broke up. It became the catalyst that finally got me out of fantasy land and back to reality. If I had cut off the contact myself, I would have saved the time better spent getting over the breakup.

If you're going through a breakup and haven't hit delete yet, you must right now.

Here are 7 undeniable reasons you need to unfriend your ex:

1. They're out of sight, out of mind

If you've recently gone through a breakup, your ex is probably on your mind enough already. If you're struggling with getting them out of your head and moving on with your life, the last thing you need is to see their recent vacation pictures or status updates.

Staying "friends" makes it so that reminders of them can come suddenly and often, tempting you to think about them when maybe you weren't at that particular moment.

2. It will curb the urge to contact

Once they're finally off your mind, it's less likely that you'll want to contact them. If they're right there in front of you all the time, it's easy to rationalize that you should text or call to mention something (anything) that is going on in their life. When it's healthier to maintain no contact, the temptation to comment when they post about the new person they're seeing can become too great.

3. You don't want to turn into a cyberstalker

There's a difference between stalking them and innocently seeing their updates without seeking them out. Even if you block their status updates from showing up on your page but remain friends, their profile is still there, open for you to look at whenever you feel weak. Few people will admit they comb their ex's profile for signs of reconciliation, but heartbroken people do it all the time.

For everyone who believes their ex trotted off into the sunset and never thought about them, this isn't usually the case. If they're on your mind already, it can get tempting to go through all of their updates looking for a clue they want you back or some news about their life. When you delete them, you reduce the temptation to backslide into a relationship that didn't work.

4. It will speed your recovery

A lack of constant reminders makes it easier for you to look within and heal from the breakup. To heal, you need less of your ex, not more. If you stay "friends" or keep following them, you're just drawing out the process of truly getting over it.

5. It reduces drama online and IRL

Not knowing what they're up to makes it so that you can't have a meltdown about them dating someone new, moving to another state, or a myriad of other things that you can get worked up about. The less information you have about your ex, the better.

That way, you aren't tempted to show that you're doing great without them or send them telepathic messages through your status updates. The less non-essential information that the both of you have about the other in the wake of a breakup, the less likely it is that their status update about their new flame will send you over the edge.

An added side effect of deleting them is that you're less likely to "vague book" information meant for your ex that will irritate your friends and family in the long run.

6. You'll "compare" less

Since you know much less about what they're up to, it prevents you from falling into a comparison spiral at the drop of a hat. It's common to wonder if you're doing better/worse than your ex, if they're dating someone new, if they got that new job they wanted, etc. After deleting them, you can't judge their "progress" versus yours after your split.

7. It makes you more mysterious (always a good thing)

If you're flirting with trying to get your ex back, know that going cold turkey and deleting them makes it harder for them to look at your profile to find out how you’re doing. If you aren't "friends," they can't look at your carefully curated "happy life" and deduce whether they should or should not contact you.

Deleting them takes away the opportunity for them to get a "fix" on seeing your information but not saying hello. This way, if your ex is going to get in touch, they will do it because they want to. It's not as a result of your campaign to show the world how you're doing or because your status update from last Thursday triggered them.
