You are in luck, 4w3's are awesome, My Girlfriend is one, the chemistry between the two types is quite good. In regards to his statement, perhaps he wants to see react to things, I've observed, particularly in 4w3 INFPs, and I'm not sure if you are an INFP or not, but it is an interesting combination, from experience I've noticed, that 4w3's tend to be a little reticent about what they believe, perhaps for fear of being criticised etc, which is an understandable response, if he is an SX 5, he probably wants you to be more honest, and more up front about your feelings and not hide them or cover them with humour. Which, 4w3's do alot

it's quite funny actually but it's something that can be seen through, atleast from the perspective of an sx 5w4 , definitely be up front with him, luckily you have type compatibility on your side (if you accept
that premise as true, but you totally don't have to).
