You're reeling from that emotionally-charged conversation with your ex... it's over. You're not sure what to think since your emotions are off the charts - ranging from sheer rage to complete despondency.
Immediately your mind turns to ice cream. All you want to do is spend the foreseeable future in your pajamas binge-watching romantic comedies on Netflix because hey, love only happens like than in real life to someone else.
Contrary to what the world tells you, it's perfectly OK to be in that space for as long as you need to.
Get those feelings and emotions out of your system - even if you have to have a few rage blackouts to do it.
You'll eventually get to a point where you can fully realize the truth about what happened. You and your ex aren't a couple anymore. It's a truth that's super-hard to accept but once you do, it changes everything.
Accepting the truth means you won't find yourself on a endless analysis-paralysis loop. You won't be living in the past, reliving every experience you had together.
Seeing the truth also means you'll be able to see the relationship for what it actually was. Maybe there were trouble spots you didn't want to see or acknowledge.
Accepting the truth also means you bring yourself to the present moment. Here you are - on your own with no one but yourself. It's not up to you to see how your ex is coping - your primary responsibility is to YOU.
Truth is something that's not easy to face let alone accept. It'll definitely take time.
I'll say this - accepting the truth about the end of the relationship is an important step in your healing journey.
