In our life from time to time there are situations when we have to part with a previously (and maybe now) loved one forever. It's always very painful and unpleasant, but sometimes it's just necessary. I have a few ways for you that will help you get through these days easier (but I hope you won't need them):

First you need to take a large box (or bag) and put in it all the things that connect you with your former soulmate. All the things that remind you of the relationship are sent to the box — gifts, souvenirs, photos. Put even expensive gifts in the box. After you collect everything, go through it again and check if you have collected everything. The things that connected you are powerful emotional anchors that will not allow you to lick your emotional wounds calmly. It's better to get them out of sight.
Now you need to do the same thing, but on a computer (or computers). Save all the shared photos to one folder, burn the folder to disk, and then permanently delete it from the computer. Put the disk in the box with the rest of the things.
Find a place where you can put the box — it can be a friends' apartment or a dacha. Many people advise you to throw away the box, but I do not advise you to do this. Firstly, there is some chance that this separation is temporary, and things may return to their places in a few days. And secondly, there may be valuable things in the box that it's a pity to throw away. In any case, in a month or two you will be able to get the box and sort out the things lying in it with a smile.
Put your phone in order — delete photos, messages and contacts that may prevent you from forgetting about what happened. The same should be done in social networks — your profile should not remind you of what happened. No need to play the "status war" — write something in order for your ex-soulmate to read it. Step over everything that happened and move on.
Call your friends — the most loyal and close ones. Tell them about what happened without going into details and without crying into a vest. Ask them to help you — you will need their attention and participation. Let them take you out to the cinema, club or somewhere else more often, invite you to visit and come to visit you. In such a situation, you can't stay alone. If the pain is especially severe, go somewhere or stay with relatives, parents, friends for a week. The author of these lines was helped by a great journey — when I arrived home, there was no trace of the former severe pain.
Find yourself a hobby in which you can throw out a stream of emotions and the free time that has appeared. Learn to play the piano, start learning a foreign language or devote yourself to sports — it is advisable to do something in the company of other people. Many people advise in such a situation to go to a dance school. Generally speaking, history knows many cases when creative people created masterpieces after parting with loved ones.

Just understand — several billion people have been in this situation before you. It's painful, hard, unpleasant — but you can survive it all. As Sam Rockwell said, parting is a great thing. It always gives more than it takes away.
