Based on the situation of this couple, regardless of them being split soon after the winning, I think the best thing to do here is to cut the prize into half so that tensions between the two parties will de-escalate and avoid any confrontation or emotional turmoil and stress that sometimes end up so badly on both of them. Ego clash won't bear good results that is why we need to keep ourselves calm and fair with others especially in a situation like this.
