Hello, well done for seeing this heart ache as an opportunity for self-growth. Breakups are tough they hurt, they make us ruminate about the past, our ego suffers, all the sad feelings you feel are normal but won’t last forever. It’s during these moments that I’ve learnt most about myself, my needs and wants and realise that happiness is only really something we can find within ourselves. While I don’t recommend dwelling on the past but maybe some reflection on why it didn’t work out will help you to let go more easily? To do this it may require learning more about yourself, do you have a hobby that you love? Do you have a project to keep you busy? Are you into travelling? Seeing new places is a great way to expand the soul. Meditation is really a good way to tune in to your inner desires and find internal peace. It does take time to heal but you will heal exactly when you have learnt/done what you have to if that makes sense. Good luck on your journey!
