Husband and wife problem

Hi, i was working in IT, after my delivery i quit job by forces of my inlaws. my kid is 4 yrs now, my husband is working near his native, my father is native bil's family also with him. i have 2 sils and 3 bils, they are very arrogant, somewhat rich, but my husband is under their control. they are not allowing me to work in IT, if i go to city then my husband also need to get transfer, then he can't take care of his father.. But my earning is needed to grow up my child bcoz my husband is low earning central gvt employee. i said i can take care fil with us in the city, if i continue my job. but they are indirectly pushing my husband to control me to not try for any job, this issue ruined our happy married life. they wont do any economical support, but they also thinking very selfish and controlling me to work in IT. my husband is saying i can go to work with my kid, he will come some time later, me and my kid sustain alone in city, he will be with his father here. but i have no trust on his words bcoz so many time he tried to leave me in married life. they are telling wrong about me with my husband and try to separate us. he also with his family side. my question is how can i continue my career? or i can leave my husband for some years? how can i change my husband who has blindly loving his family not consider our growth..
