If he's your ex, what you have to do is cut off all form of contact with him, take the time off to do the work and heal. Analyse your mistakes in the relationship,place better boundaries, non negotiable and standards for yourself. And to do all these you have to take the time to really know and discover yourself for who you really are, not whopthers want you to be or who you think you are. Once you've discovered who you are then you can know who you want to be and work towards it.
I wish you ❤️ & 💡 in all your future. endeavours.
