The lady may still have decided to stay with the man, as she may have already spent months or years together with him, and to break up with him may not seem like a wise decision to her. However, if they have wise or elderly people around them, I don’t think they will break up but will take the marriage until another time when the man is able to generate another set of funds for them to settle down and marry her. The fact that she loves the man to the extent that she decides to marry him is why she won’t leave him because of this incident that happens.
However, the guy may think betting with the money is a wise idea, as he believes if he wins the ticket, he will get more money to add to the wedding. Just that he made the mistake of putting almost complete or complete if the money, which happens due to a lack of control over his emotions, I believe he has learned his lesson now and will never do something like this again because this is an unforgettable story for both the man and the gal.
"A thousand good things that have been done can be lost just because of one mistake" which proves that it is so easy to destroy a trust that has been built and maintained for many years. While this is not a small problem, it is quite a big problem because the man behaved carelessly by losing quite a large amount of money just in one bet. Meanwhile, to be able to collect that much money, the woman has to save for months and maybe years to be able to have that amount of savings.
And I think the woman will leave the man, because it is clear that the man is not capable of responsibility and does not want to try more to get money so he can get married. This man deserves to be left behind and this woman deserves to get a better man who is someone who can be invited to fight together.
