Hi lala_tart,
Thanks for posting your questions and telling us about your situation. It can be very hard and extremly frustrating to live with someone who you can see has a problem but will not admit to it.
To find out if the software is legal, if you are in New Zealand, you can call the Department on Internal Affairs, 0800 257 887. Also you can make complaints to them as well as your local MP. If you believe that your partner is being targeted in a scam then you can call the Commerce Comission on 0800 943 600.

OurProblem useful to find out ways that you can talk to your local MP and to work with others in the community to make changes in the community.
I am wondering what supports you have and how are you protecting yourself from the harm that the gambling can cause? How are you protecting your assests?
If you live in NZ you can call us (Gambling Helpline) for free on 0800 654 655 for support and for some other suggestions around what you can do. There is free one on one counselling for you if you want to go and have a chat with someone.
Once again thank you for sharing what you are going through and remember that you can post here for support at any time. Feel free to post again with how things are going.
