Nobody is forced to accept his/her partner to be a gambler, because people have different views on this matter. But it's a must for everyone to be transparent and genuine to their partners. If they are gamblers, they have to openly tell this, so the relationship can grow stronger based on mutual trust, or the relationship can also end before getting too serious, due to the another side not accepting a gambler as partner.

Being transparent is very important and always avoid lots of problems in the future. If people were more sincere since the beginning of their relationships, we would see much less couples facing issues and divorcing later.
