Imo this is so low to bind everything to money in family or relationship. Its an endless battle of silly arguments and counterarguments. One person can blame other for being addictive gambler, other person can always name something where first person spends money recklessly on. For example wife complain because husband gamble; husband can complain because wife spend to much on cosmetics. Whole story can be turned upside down so simple. I can complain on wife spending hundreds on thousands on shampoos, masks, collection of creams for every part of a body and so on, and so forth. When husband has huge 2 in 1 bottle of shampoo/body gel, purchased with discount and tooth brush. Nobody divorce because wife spends a lot on cosmetics.
Some of the problems when gambling in marriage is,
Lying to hide the extent of gambling,
Forgetting important occasions lost of time and energy in gambling,
Being unable to focus on the partners or shared interest.
In extreme cases, a problem gambler can get irritable and angry when not betting, which can manifest as aggression and violence against a loved one. In addition, they may steal from their spouse to recover losses and/or fund wagers.
