Consider a situation like this There is a rope of uniform mass $M$ whose one end is attached to a wall

Ofc gravitational force $Mg$ and normal force are acting on it in vertical direction (that's not our concern)

My real concern is:

When I "push" on the rope, basically apply a force on the end of the rope in the direction of the wall,the rope slacks

My simple question is, since I apply a force $F$ on the rope(or more specifically on the atom which is at the farthest end of the rope), what is the Newton's 3rd law pair/reaction force of my Force $F$?

Now, even with the basic knowledge I have,that reaction force can't be tension as the rope is slacked,and under NO way a slacked rope can produce tension

So yeah,my doubt is what's the 3rd law pair of the action force,which is me pushing on the rope with force $F$

Also,even though this question seems to be not so good,but can someone explain why I don't possibly feel that force on my hand?

Now, with my basic knowledge, I have deduced that reaction force can't be tension as the rope is slacked, and there is NO way a slacked rope can produce tension.
