我认为这里是倒装
caught 和as不是连在一起的
I complained an【← 是and吧?】 made my husband miserable,caught as he was between the people he loved.
正过来是：
as he was caught between the people he loved.他被夹在他所爱的人之间
整句：我向丈夫抱怨,令他因被夹在他所爱的人之间而痛苦不堪.
【我脑内YY 是媳妇跟婆婆吵架了?!= =】
虽然我不是特别理解这为何要倒装 不过我觉得只有这样我才看的通...才疏学浅 不保证正确
当然还有一种更不靠谱的理解 就是miserable和caught之间的逗号是and的意思 那就变成了：
I complained and made my husband miserable and caught,as he was between the people he loved.
caught就单独做一个形容词 但是还是和as不是连着的 【这个真的更不靠谱了...
