"X nggak ada apa-apanya dibanding Y" normally being used to compare, means

"X is nothing -- compared to Y" ==> "Y is way much better than X".

"Wah, itu sih nggak ada apa-apanya dengan suami saya". 

I am not sure what is the context of your sentence, but it might mean 2 different things:

(1) "that" has nothing to do with my husband.

(2) "that" (should be someone else) is nothing -- if you want to compare him/her with my husband -- my husband is way much better.
