I remember feeling just the same as you!
Try not to get too stressed about making your LO go to 3hour easy, mine didn't get there properly until about the 3/4months mark as hard as I tried to make him!
These things happen in their own time and you cant force your LO into a regime. Read her cues and gently coax but if it all goes wrong don't get disheartened, there is always tomorrow to try again. Try not to fit easy into a time frame but just take each step at a time letting each one use up as little or as much time as it requires. As your LO gets used to the rhythm of easy you will be in a better position to worry about your timings.
Breastfed babies do tend to take a little long than bottlefed ones to get to three hour easy this is due to BM being eaisier to digest, so don't compare yourself with others as everyone is different
It sounds to me as if you are doing a great job allready so just relax and enjoy your LO
