Hi Jakeski – it seems like you have taken the first step to realising you have a problem – i.e. admitted to someone that the problem exists.
Obviously your gambling is affecting your relationship – but I have to ask, do you want to stop? If so, then there is advice that we can give you, but it will have to be done by you – and it will not be easy …
Your fiancee may wish to look at the friends and families forum on here and decide if she wants support for herself. Both of you working on the problem might be powerful when things get difficult, but that will be a decision for her. I will leave it there for now. I am sure you have read other posts on the forum and know what practical measures to take – but I think you have to answer the question above first.
