Know each, fall in love n marry then...dirvoce!!wat for?!

i felt a bit sad today since i wacthed a taiwan show by jacky WU just nw!! this show is for those ppl who has family or personel problem and hard to slove with themself. During the show time, Jackey Wu wil try to help them n solve the problem as much better as he can or to settle the result with a happy ending la~BUT!! today's case, is about a couple married after 5 years n still cannot have pregnant, somemore, that the husband's mother very angry n ask his son to dirvoce with his wife and fine one more women form outside.
if la, u really love ur wife, u wont listen to ur mother la but u KNOW !! this husband is quite bad bcs he really follow wat his mother said, to has one more women outside. then Jacky Wu asked him why u do that, he was answer" oh, is bcs the outside women love me very much n she can have pregnant with me, and i hate to go bak home bcs will see my wife and my mother fight with each other so i better go out to fine outside women!!". his mother after know this was feeling very happy n agree his son to bring back that outside women back.
i am thinking wat kind of husband of this. he didnt support his wife and let his wife get bluy by his mother. somemore, he says to his wife like that" to u !! i am not interested at all nw"
can u image hw sad his wife when she hearded that?! They know each other and fall in love...and felt want to be together with each other forever ...then get married. all the process is sweet and love...but nw how come like that ady?! i really distrust why they can simply to beark up just bcs of "CANNOT PREGNANT"?? from here , i really cant see "WHERE IS TRUE LOVE"
