I don’t see any reason for you to be confused over this issue. Shari`ah condemned Nikah al-shighaar because it resulted in injustice for the women involved: This is the case when each marriage is entirely dependent on the other in such a way when the mahr of one is the marriage of the other.

 

As I can I understand from your question that was not the case with you.  The only fault was they did not consult you. However, since you were an adult and you never objected to it, there is no reason to question the validity of the marriage.

 

I would advise you not to pick and choose fatwas.

 

To make decisions in critical cases such marriage and divorce would be like someone acting as a jury, judge and executioner at the same time.

 

While stating this, I assume that a recognized Marriage Officer or imam solemnized the marriage in conformity with the laws of the land you reside.

 

So, don’t confuse yourself by random readings of such issues.
