Tell their friends or social media contacts you're doing well if you see them. Do not discuss your ex, the split, or your struggles. You're chatting to their buddies, therefore they'll tell them everything.
Date if you're ready. This will make your ex jealous and heal and restore your confidence. This dating tip works for short-term relationships. Waiting for them wastes time.
Grieve your ex without difficulty. Vacation and treat yourself. Take a break, clear your thinking, meet new people, do new things, and return refreshed.
