Much has changed since last November, when Afghans were praising Pakistan for saying it would no longer support the Taliban and would instead work for peace.
"We believe that relations between the two countries are deteriorating," says Aimal Faizi, spokesman for President Hamid Karzai.
Faizi says the downward slide started last month. The two countries had agreed to convene a conference of religious scholars, or ulema, to denounce suicide bombing. But the conference fell apart at the last minute, with each country blaming the other for undermining the effort.
