MCA he is married

Paano mo sasabihin sa ka chat mo na alam mong married cya. Should I inform his wife? Or should I ghost him na lang? 🤔 Ako 33(f) and 40(m). We met sa dating app and met personally na rin and went out. Nothing happened momol lang, but we kept in touch until now 3 yrs na. Recently ko lang nalaman na married na pala cya for 10yrs and one adopted kid. Nasa US na cya with his wife and ang malala kamukha ko pa wife niya 🤭
