It's been 17 years. They've done literally everything they could, and still lost. It's only going down hill from here because the Taliban currently control more land than before the invasion.They've spent one trillion dollars+ since 2001 in Afghanistan. At this point their pride is on the line. That's why you won't see them withdrawing anytime soon.
The sources of Pakistani's water is in Afghanistan, and a secular Afghanistan (who also have a good relationship with India) is a threat to Pakistan which is why they support the Taliban who they have a lot of influence over.
