What should I do? I'm very confused?

I say you meet up with him and tell him how you feel. tell him it's too late now. . you've m oved on. don't do it over text because that just shows how much you eally dont care, you know? but tell him in person, gently if possible. you cant use the excuse of not wanting to ruin the friendship because by the looks of it, the friendship was long lost a while ago.
