Sorry to hear about your situation.
It would be hard for me to tell if he is using you or not. but i can help you think furhter and suggest ways to better your life.
1) please seek some counselling. you need someone to hear out your enitre story to be able to tell if he is only using you. A local Aalim is a good option too.
2) praying will really boost you and make you a stronger person. so keep up with that. indeed remeberance of Allah brings Tranquility.
3) from what i can tell, you are also stressing yourself out for no reason. it is true that your parents will be heart broken if you split. but that does not mean that they wont accept you. i would suggest you patch up your relation with your parents regardless the outcome of this marriage.
4) if there is any person who is influential on your husband, then you must speak to the person so that you can get some straight answers and move on in life. the middle man can help you understand your husand's thoughts on this marriage and if he is serious at all?!
