Hello Bailey, and a warm welcome to the forums.
We can't say whether or not your partner has put into a position you're now in, only because you have joined them, however, there does become a point where it's so difficult to say 'no more, I want to stop all this drinking, gambling and travelling.'
These addictions will make you lose control because once you start, you give in, and procrastinate until tomorrow, saying 'I'll start then', but it doesn't come.
AA may work for many people, but for some, it doesn't address their own depression or they can't relate their own situation to what has been said or their 12 point plan, and that's what happened to me.
You won't know how you feel, only when your partner wants to continue on with these addictions and to say 'no' will take courage and all the strength you have, but to gain this you will need help which I'd like to you about if you can reply back to us.
