Dear Mookie
I don’t find your mind closed or judgemental – I think you have every right to be very concerned about your boyfriend. I think it would be worth your while downloading the GA – 20 questions which you can find in ‘Resources’ at the top of this page Click on to ‘Resources’ and in ‘Location’ scroll down to ‘world’. Click ‘Gambling help’ and then ‘Search’.   Scroll down to ‘Gamblers anonymous – Twenty Questions’. Most compulsive gamblers will answer yes to at least seven of these questions.   In my opinion most members who have lived with the compulsion to gamble will also be able to answer yes to at leave seven of those questions which hopefully will help you to ‘know’ what you are, or are not, dealing with.
Compulsive Gamblers are normally charming and lovely – it is their way to get the enablement they need to feed their addiction.
Unfortunately Gambling Therapy is not funded for the UK and although I appreciate how difficult it was for you to write this thread I am going to have to direct you to gamcare.co.uk for your support.   Please cut and paste your post – you should talk about your situation further.
I believe that when you are in doubt with the addiction to gamble you should do nothing until you have knowledge of it because knowledge will give you power over it and help you make the informed decisions that are right for you.    
Your boyfriend is very convincing but the addiction to gamble is the master of manipulation. There is in the UK a fantastic rehab, the details about which can be found below this forum in ‘GMA residential treatment Q&A’. You will possibly feel this is a bit too much for your boyfriend at this time but I mention it because it was where my CG went and changed his life.   If in the future your boyfriend needed a signpost to recovery then knowing about the Gordon Houses will be good for you.
I do wish you well – below this forum we have a Friends and Family topic forum where we have focussed on different issues that affect those who love CGs – you are welcome to go through them and see if there is anything to help you.  
I would not be writing on here if I didn’t know that the addiction to gamble can be controlled.  
Gamanon, the sister group of GA is also available for Friends and Family of CGs.   It was where I found my salvation.
Once again – I wish you well
