Having problems on bottom lane

Here's the thing. I have been trying to main Leona and thus far it hasn't been going well. I've been sticking to AI mostly with a few normal games with her trying out some builds to see which is better and faster to use. The problem comes in from my ADC, but first let me tell you how I feel Leona should be played.

It seems to me that Leona, being a melee champion, is meant to rush in and secure the kill for the ADC. Her E being the main initiator and her W gives her the tankiness to be able to come out alive but only for the initial onslaught. It also doesn't hurt to have that damage thrown in at the end of the first 3 seconds. In order for this to work though, you should wait for the enemy bot lane to make a mistake and subsequently make them pay for it by initiating and then having the ADC come and finish them off.

The problem is that the ADC doesn't follow this chain of events and I almost always end up dying because my bot buddy either doesn't understand his/her role or just flat out refuses to do what they are meant to. (I actually had a Graves ADC who told me to stop and just poke for now. WTF) As such, I've been yelled at in game and possibly reported for "intentional feeding" because of the shortcomings of my ADC. I'm not perfect with this champion and I do make mistakes in judgement but I just want to make sure that my train of thought is sound on the procedure of the bottom lane with Leona.
