I have a hdhp through my employer with a HSA. Dh is on his employer's insurance with a PPO. They just started offering a FSA this year. He signed up for it, not realizing he wasn't allowed to since technically he could use mine even though he isn't on my plan. We are nowhere near the limit of either account. Is there a way to fix this? Or are we majorly screwed? I appreciate any advice anyone might give.
