Dont understand why fl cannot do a dna test

#1

In this novel I find it really stupid especially from fl side that if her son keeps on saying so seriously that ml is his dad then why don’t fl do a dna test to check it, how can she be so sure that it can’t be ml, afterall girl you didn’t know who was the person who slept with you 5 years ago, from ml side i can understand because he didn’t know her history, but fl just keeps ignoring her son’s saying because she thinks he is a child what did he know, how stupid. If I were in her place i will definitely do a dna test because he only call father to ML.
