I read what the OP wrote well, which is why I wrote what you see in a bit. I didn’t understand the concept of the topic, but I was taking advantage of the strategies that she can follow in order to tell her husband, and if she knows that her husband is the type of person who hates gambling, she shouldn’t tell him because he will stop her from doing the gambling, and if that happens, she will find it hard to stop. Because based on what she wrote, she already has a good understanding of gambling, and she wants to use this opportunity to inform him if he will be interested in joining because that is the main subject of the topic, so with consideration, you are supposed to know that she is willing to invite her husband to gambling because she thinks it might be very helpful for them.
There are always consequences if we hide something from our partner, if we don't act on it immediately, the results are usually not good. in this context, a person continues to gamble and keeps secrets from their partner. Telling the truth is not as simple as we discussed, especially since we really know our partner's background. Let's just say that our partner doesn't really like gambling, that means we know the other consequences that are at risk for the relationship that has been built. In fact, each case will of course be different, because each person or couple has a different perspective. We even know that gambling problems often have an impact on our relationships, it even seems like those of us who already have partners have experienced problems due to gambling.
OP created a thread for us to discuss, some of the points are as you concluded. also, if we refer to the question title of this thread. although, OP says that he has understanding and tips for gambling responsibly. It's just that it's not easy for our partner to understand the point of view we give, especially if we invite him to get involved. For me, there is no better trick than for us to decide the choice ourselves. I mean, gradually our partner will realize or know about it. either because of our carelessness, or we are the ones who cause problems with our gambling. Well, having a dialogue or discussion with your partner is very important, including things that are entertainment in nature such as gambling. instead, a person can act as an alarm to their partner so that he or she remains in control and can be controlled over his or her gambling. provided that nothing is kept secret, and each partner is allowed to correct it. if it can be done, not a bad idea I guess.
