You are fucked. You can't read him, he can't read you. Fucked basically. Nobody is a mind reader. Key of reading people is rather easy, intuitive, but people are ignorant and generally ignore most things that go around them before it is too late (they are on autopilot basically). If you miss out on initial contact and basically don't pay attention then it shouldn't come as a surprise why most people regardless of gender are absolutely clueless what the fuck is happening around them. People just don't observe. Everything seems to be background noise for them until it isn't any more (the so called autopilot state).

If you want to read people to get more insight what they really want without asking them, then all you have to do is stop your autopilot from engaging and actually observe. Observing and seeing things too late is not good enough. You need to really see initial behavior of a person so you could compare it to w/e status the person is at currently, thus giving you an idea what actually changed, which in turn can lead you to answers such as what did you do or said that triggered the change in their behavior. Put 2 and 2 together and congrats you just successfully read another person first time in your goddamn life.

So my advice is simple: train yourself to pay attention (replace your lazy eye with a trained eye) or alternatively get a third person to observe for you - this way it is easier since the person probably doesn't know and thus doesn't have time to put up their shields, which will surely give you a better insight to his mind. Mind reading might not be possible but reading and observing very much is. The same technique is used by professional interviewers to observe the change after they trigger a response through questions. Very much same.
