I would imagine that the time you are hurting is not necessarily wanting the relationship back but instead almost grieving the happy times together.

When you feel this way just remind yourself why you made the decision you did and how you can move forward in a positive way

for me that would mean cutting that person out of my life for a while so I can healthily move on with out clinging to the relationship. For you it might look different.

I would say just focus on healthy habits to invest in yourself or in the people important to you. Self care. Self improvement, new hobbies, join a new community, try dating new people. Anything to keep focused, positive, developing, learning moving ahead and not dwelling on the past.

Invest yourself in something that keeps your mind off of it.

get a pet or pet sit or babysit or join a meet up group.
