Would you send flowers for a wedding under these circumstances or a card?

My best childhood friend , 60, is marrying her long-time boyfriend, 75, this weekend for one reason: he wants to obtain Medicare on her account even though he’s very wealthy. They’ve been living together for thirty five years and he always refused to marry her until his health began failing two months ago. Now he has tremendous medical bills he can easily pay but tries to avoid.
Would you send flowers or a card for this marriage for benefits? He says he doesn’t want flowers or music provided by the church; just the ceremony so he can get Medicare. He has never worked a day.
