suppose we r drawing a free body diagram of a body, then we consider all the forces acting on the body but we dont consider the force whichthe body is exerting, y?//

indirectly ,the force which the body is exerting is also included as by Newton's Law for every force ,there is equal and opposite reaction hence when we show reaction force we indirectly show force exerted by body

we also consider the force that the body acts upon.that force is the weigt and in some cases the horizontal force

because at that time we consider that body as the system and take into account only the forces acting on the body and not the forces exerted by the body.
In that part of HCV where the procedures of drawing a free-body diagram are given, it has been clearly discussed with reference to the horse and cart problem why we take into account only the forces acting on the body and not the forces exerted by the body.

Suppose that a person A says something bad about the person B While doing so he doesnot bother what he is doing what bothers him is the reaction of others. Similarly while drawing FBD, it doesnot matter what force a body is exerting. The thing that matters is the forces that the external agencies are exerting on the body.
