My theory is that Huntsmen and Huntresses are considered 'married to the job'. Whilst they may choose to raise a family, they may choose to not do so.

It is not uncommon for a Huntress who wishes to focus her full attention on her calling to give up a child for fostering, either with the child's father or a different family if she believes that is a better choice. It is not unheard of that they may even choose to sever all ties with their child so that he or she is not cofused by having 'two mothers'. It's my guess that Yang's mother decided to put her calling first and left Yang with her father. When she realied that Summer was very ably taking on the 'mother' role, she decided to move on rather than cause tension by demanding a mother's rights.

It's possible that Yang's father might have broken a long-standing tradition by telling Yang the truth of her parentage.
