I have a friend after years of knowing him we moved away without reason After 5 months I returned to tell him that I love him

He said that he is in a relationship with a girl he knew her before me

We stell in touch and after months the girl left hom and he's broken heart and he still love her and I do still love him what can I do?

I think you should be there for him until he's good and ready to see people again, and then tell him how you truly feel about him. :)
