advice?

is it possible to move on from someone and still see them and talk to them occasionally. me and this guy i was close friends with and we’re in the same friend group started a “situationship”

i basically fell in love with him but he lost interest. he stopped texting me almost completely but if i see him in person he will act like he still loves me.

i want to move on i just don’t know how to do so and still see him and talk to him.

i just don’t know how to be his friend after being together as more than that for so long.

he never told me he doesn’t care for me anymore i just know because he doesn’t talk to me like he did.

i just deserve better and hate how wishy washy he is.
