如果真如您所說的，一般各州對於這種情況都有規定

重要的是您必須有證據來證明您所說的。
以加州為例加州婚姻法2201 就規定如果一方拒絕履行婚姻義務達五年以上，這個婚姻就可以經由法律程序宣告無效
原文如下，
2201. ) The former hu*****and or wife (i) is absent, and not known to the
person to be living for the period of five successive years
immediately preceding the subsequent marriage, or (ii) is generally
reputed or believed by the person to be dead at the time the
subsequent marriage was contracted.
(b) In either of the cases described in paragraph (2) of
subdivision (a), the subsequent marriage is valid until its nullity
is adjudged pursuant to subdivision (b) of Section 2210.
所以您需要諮詢律師看看您所在州的規定與處理的方式。

不過老貓對您所說的確實有很大的疑問，但是這不是我們需要討論的重點，希望您本著天地良心做對的事情。
