In american housewife is oliver gay

No one is surprised that Oliver is gay. When the rumor that Oliver and Cooper are dating gets out, both characters decide to lean into it because they think making Oliver a "minority" might help with his college application.
Not that gay/bi teens are always upfront (and may not be comfortable talking about it) but they've made an effort to show that Oliver has grown and has a better relationship with Greg and Katie than he did before.
