Why would you not feel sorry for the lady?, She was betrayed by her fiance, she trusted him with her finance and he spent all of it on gambling without her intention. She was planning for their future and he used their collective funds for gambling activity. He should be arrested for that honestly. He chose gambling over his marriage . If I was the lady, I would really feel very bad and might end up calling off the marriage because that man it's never to be trusted. His irrationality is just too much.
If you want to take risks, then be sure to take it with your money and not somebody's funds. What he did is totally wrong and shouldn't be encouraged at all.
Why would someone be arrested for spending collective funds? I my wife takes money that I have left on table or just at home, go buy food and eat it herself, should I call the police, because she took and spend them?
This is a very wrong analogy of the situation, it can be compared to you as a married man kept in the custody your wife the bank Card of you guys collective funds without any other money elsewhere and she goes and withdraws all your life savings and hers for ponzi, meanwhile you've the intention of using the money to buy a house or another meaningful investment that would profit the family, reply me how happy and approving you would be of her behavior.
In fact, we dont know the motives of that man. What if gambled to get even more money and make wedding even better? What if he would won, pay for the wedding himself, and return his future wifes part of collective funds? He would be a hero than. But in this story, he has lost and now is a bad guy. That man made a mistake, but everyone think that he has done something really awful. That is just money.
Whatever motives he has is rooted in stupidity, even if he had won the money, his stupidity would've lived him tho trying again and again until he hits a rock and he'll be back to a messy situation. He has done something really awful by taking uncalculated risks and costing his partner of her dream wedding which she so much anticipated and working towards. If he can do this at the start of the marriage, we can only speculate the level of his carelessness and irrationality going forward
