we can't go one day without some ass takes in here huh
Vegeta's entire character arc in Z was about developing things more important to him than his ego and moving past his innate desire to be a ruthless Saiyan, and subjugate others the way he was subjugated by Frieze, Bulma contributed a lot to that development.
Him dropping a fight he didn't need to be in for someone he cares about more than his pride and letting Goku, who is much more equipped to deal with this situation is fine, if they were really in danger with no other option we know from other examples that he would override Bulma and that Bulma wouldn't interfere.
It was also just a comedy scene, there's nothing emasculating about dropping your ego for a spouse, that's just maturity.
Let's not act like Naruto and Sasuke wouldn't sleep on the couch like good little boys if Hinata and Sakura were mad at them.
And while Adult Sasuke isn't his writing peak at all IMO, he's still a good character and mostly utilized well.
