Would you speak up if one partner invited an ex to a private celebration without mentioning it?

#Situations

This is a fictional discussion scenario set in Singapore. It involves two people whose relationship is becoming serious.

The central problem is that one partner invited an ex to a private celebration without mentioning it. What nobody else knows is that the ex helped plan a surprise that cannot be explained without ruining it. About S$1,200 is also at stake, and screenshots are already circulating in their friend group.

Then it becomes clear that the other partner had previously asked for complete transparency about this ex. The difficult part is that the intention may be harmless even though the secrecy broke an explicit boundary. The person at the centre has to decide before the situation becomes public.
