bunnyhoney you said your husband is pissed off with you because you are not their with him. but why?
everyone in pakistan understands it takes time for them to be sponsered and he also must know that you have a life in the USA.
why is he and his family getting upset with you that you are not there?
also i agree with one thing STP bro said. not only in pathan culture but also among punjabis a man's dominance over women is emphasezed so i wouldn't be surprised if his friends aer telling him to not give you any bhao. ej tho you are a woman on top of that you live abroad and you probably have a busy life(education career) so this threatening his manly superiority over you.
as for what to do he will probably get better with you when he comes over as it is probably his surroundings and the situation which is frustrating him and bringing out his insecurities. but be prepared for a tough future ride as your guy seems a bit rough on the edges. but now nikkah is done so just suck it up and deal with it with sabr.
