This is because you are One with your Twin Flame at the core. You heal your Union by healing yourself.
Learning that your relationship with the Divine, with God, with yourself, is actually what you are prioritizing. Union with your Twin Flame is ultimately a reflection of the Union that you cultivate within, with yourself, with God, with the Source of all Love.
When you focus on trying to find Love outside of you through your Twin Flame or others, you are looking in the wrong place for Love. This is what leads to the pulling away and separation. Your Twin Flame is showing you that you need to go within and heal.
The solution lies in focusing on filling your own cup first. Prioritize self-love, self-care, and commitment to your healing. Cultivate a strong connection with yourself, and God. Union with your Twin Flame reflects the inner Union you foster within yourself.
