I dont think there is something wrong about being single mom. but her reason for re-marrying is wrong. You don't marry to look for someone to provide for you. She should learn to provide for her kids too. Sa hirap ng buhay ngayon, dapat both husband and wife help each other to provide for their family. di na yung lalaki lang. But if her reason is to find someone so she can have companion, I guess okay lang but looking for a partner to have someone to provide for her and her kids is a no no.

Just my two cents.
