he needs me

after 4 months of break up, my ex's health is really awful. he started smoking and doing it a lot. I didn't talk to him since we broke up and didn't have any of his news until today a mutual friend called and said :"you need to see him urgently he's so sick he lost a lot of weight just do it " please tell me what to do 🙁😢😢😢 ps: the relationship hurt me a lot and yes I started feeling kind of guilty even though I was broke into million pieces when I was with him it wasn't healthy at all 💔 and thank you so much for your support 💕💕💕
