That shows you have a happy relationship with your boyfriend.
The easier things are for each other to understand, the stronger the relationship. Whether gambling is bad or not depends on the player's perception. Just like using any tool, if you can control it, you don't have to worry about social prejudices. Even if a couple has the same gambling addiction but still doesn't leave each other, we all understand the power of love that makes us accept all the strengths and weaknesses of the other person, especially that harmony in each other's level of cognitive bias, the relationship still maintains.
The key is mutual understanding between both parties, both from ourselves and also from our own girlfriend or wife. Because whatever can be controlled better by not paying attention to other people's words and also not making more unnecessary publications, I think any relationship will still be fine and there will be no commotion that is detrimental to each other. I also agree with what you say because when we can understand each other in any case, there will never be chaos in any relationship even though we also don't need to be so addicted to gambling if we don't really need it.
