Recently, a Sinhala movie called Yasodara was released. They used a lyric stated as " She is the Buddha’s chastity", which is wrong.
The question above sounds the same.
Was Buddha an irresponsible husband and a father?
This is not the way that you should ask the question!. In the western perspective, this may be considered right, but the bodhisatta and the Buddha are not the same. Buddha was passionless (Vītarāgī)and had no bonds with others.
Therefore, you would rather ask the question as,
Was Bodhisatta (siddarta) an irresponsible husband and a father?
