 * Tai and Summer dated at some point


 * Broke up


 * Tai got with Raven


 * Had Yang


 * Raven left


 * Tai is alone with an infant, his first child, struggling


 * Summer moves in with him to help


 * Tai and Summer work together to raise infant Yang, acting like parents together


 * This rekindles old romantic feelings


 * One night, a moment of weakness turns into a night of passion

Given what we know of the character's mindsets, I wouldn't be surprised if Tai and Summer had feelings for one another, while Raven and Qrow respected their individual talents;
 * Whoops, Ruby is conceived

Thus Raven decided to outdo Summer by taking the target of her affection(possibly after being told about them by Summer) and boldly engage in a relationship with him first(to show she was the strongest), which eventually failed because there wasn't enough love there on either(both or one) side, possibly leaving the others because when Tai left her and accepted Summer, it made Raven feel as though she was being shown to be weak, which Raven's ego would not allow for, so her mind blocked out that past life and now only concentrates singlemindedly on her life in the clan.
