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.
This are not couples, but boyfriend and girlfriend. This has just justify that some ladies aren't in relationship because they want to or they are dear because of love, they are their to find a man that can help them offset bills, you can see that everything change immediately as soon as she won the money, she is no longer interested in the guy or the relationship again, this is to tell you that ladies are only loyal to their feelings and not any man sacrifices. If it was the guy that is in her position, he might want to give her some share but she is not ready to give anything, very selfish set of human.
Have you ever tried something like this situation before?
So what is your thoughts on this, 50/50 good for you or nah?
Will you insist to have an ego battle if you are on the same situation?
If your answer is yes then Why?
And if no then why not?
What are the things you would do to resolve the issue?
How do you think you can handle this kind of situation?
I have never been in this kind of situation but even if am, it's very logic to say that to share together. If you aren't ready for this kind of situation, it's better you do it independently like your phone to avoid this embracement. If I am the guy, I might as well as free her and let her go instead of been a sensational headline for media to spread around my picture about my girlfriend and I running to share money.
