AVENGERS INFINITY WAR THEORY WHY HULK GREEN DIDN'T COME OUT

Hulk is a Giant Green Monster.. but he has its own thoughts and emotions .. Bruce Banner is Hulk but their minds are separated .. They are sharing a single body.. in Infinity war we saw hulk resisting to take control over the body and mind..why?? is this because he is scared or he is just fed up listening to Bruce mind?? well, here is my theory what really happen,

My theory about hulk:

In Thor Ragnarok, Bruce said that he always has controlled over hulk but recent two years he didn't know what happened..

Well so before age of Ultron we didn't really saw hulk really communicating with anyone.. He just knows smash smash and smash.. In the age of Ultron, we saw his little interaction with black widow.. And I also think not only Bruce but hulk mainly hulk fall in for her..

But after scarlet witch manipulates bruce.. She actually triggered the hulk's emotions.. So even after hulk buster bring back bruce the effect was still their.. And that emotion gives hulk enough power to don't let Bruce control over him..

But in that process hulk didn't just get his character development but his feelings grow.. Like when he told thor in ragnarok.. Earth hates hulk so he doesn't wanna go..

So during those feelings hulk became aware that Bruce just using him and not letting him connect with others..

And that's why he didn't wanna come out in infinity war..

Here is what I think happened..
