Fix an ESP8266 (ESP8285) Circuit

I am trying to build the following:

An ESP8285 is connected to a LiPo via an LDO (3.3V).

A SHORT button press should latch power to the ESP8285/ESP8266.

The problem is that the latch circuit is always on, even when the button is pressed.

The circuit needs to fixed so that:

1) The short button press latches power to the ESP. (Power usage should then be 0)

2) GPIO16 or another GPIO, can unlatch the circuit, thereby turning off the ESP itself.

Attached is the circuit, in which the power is always latched on.
