My assumtion is that she is helping Qrow, Ozpin, and Ironwood with taking down the bad guys and because it was so dangerous, she had to leave Yang and her father. Of course, that is assuming Summer or Yang's father didn't know, given that they are on the same team.

That, or she didn't think she could handle being a parent. Either one works. Probably less Darth Vader and more Haytham Kenway. While Darth Vader doesn't try to relate to his son but redeems himself anyway, the Haytham Kenway would try to bond with his son and try to get him to the dark side but never repent himself.
