hi allyn,
i was just reading your post and i can't help but feel so sorry and symphatize with you. you shouldn't really let them do this to you, and that you shouldn't suffer alone. seems to me that your husband doesn't have the balls when it comes to his family. for a start it's wrong to let your in-laws treat you like the way they are treating you and that your husband should side with you and not with them. what happened to your marriage vows?
may i ask what is your status in the uk? i know it may seem to be out of the question but it would also help what are your other options other than to go back home. are u on ilr or still on settlement visa? do u got friends where you could possibly stay for a while?
seems to me your husband needs kicking in the back side to make him realise how lucky he is that he got you.
sometimes you have to say enough is enough and be heard. you married your husband, u didn't married his family. like what others said save some money looks like you will need it soon.
