Don't really think its the gambling that causes relationship breakdowns, its when partners or family members are kept in the dark or deceived, which breaks the trust that's so essential in any relationship. It's up to us to make informed decisions, to be self-aware of our behaviors, and to ensure we're not crossing lines that jeopardize our relationships and personal well-being.
The root cause of getting that problem is because of the gambling participation and we know the possible after-effect of it.
I get your point but without participating chances not to fall to any of this can done, you need to play with responsibility if you want to keep
your relationship, like what you mentioned, once there's already something happening in the dark.
Meaning to say that there's a problem with handling the situation in your gambling activities, it can spark the problem and may affect your close
relation with your love ones.
