We also have to take in note that all we know about this is from Yang's POV. Taiyang could know the reason why Raven left but refuses to reveal that to her daughter. After all, Yang doesn't even know the name of her own mother so she's probably in the dark about everything.

That includes the reasons and circumstances of their marriage and how they got separated.
