Esp8266 Esp-01 Forgeting sketch/not responding after restart

So i have an esp-01 module and i am able to flash it successfully by using the Arduino as a serial bridge(connecting RST of Arduino to vcc) the sketch uploads successfully and works but the moment i remove the GPI0 pin from gnd it stops working if I try to cut the power and power it again it stops working I tried removing the power and connecting GPI0 to 3.3 v still no luck here's my circuit diagram:

ESP GND => Arduino gnd
ESP VCC => Arduino 3.3v
ESP TX => Arduino RX
ESP RX => Arduino TX
ESP CH_PD => Arduino 3.3v
ESP GPI0 => Arduino gnd

What about GPIO2 ?
It should be pulled up too ...

When i put GPI02 to the 3.3v line the chip refuses to take any information I can't even flash it and i don't get the blue light which i get when i ground IO2
