This fails to create a stake that can carry a plot - terminate the pregnancy, end of story.
Unless, of course, she refuses to terminate, in which case the onus is on her to raise the child without a father - it ain't going to be nice, but once again his career is unaffected
Sorry for the cynicism but if they can't afford to raise a child they should not have it - now day and age one has to be real.
There is no existential quest here, just a matter of prioritisation, career or family and he clearly prioritises his career over family - so, there, question answered...
I simply can't see a plot that can sustain a feature in this.
