Personally, I'd ask about it. Gently and non-accusingly.
I've had a look through your previous posts, because your mention of 'troubles' had me wondering. One thing I wanted to point out and highlight to you:
When we stuff up badly, we hurt those around us. Badly.
When we realise that we've stuffed up and decide to turn our lives around, sometimes we look at others around us and see their lack of growth, their clinging to the past... and get impatient. But we generally forget just how long it took US to see the light... and we forget to give our loved ones time to catch up with the changes and realise that they're longterm.
We have a tendency to forget just how much harm we did 'back then' and expect everyone else to bounce back from our destructive behaviour. Usually it takes the victims a lot longer to recover than the perpetrator.
It might seem really unfair that I'm focusing on you and your old mistakes here. In one sense, it is. You're a different person now, you've grown, God's forgiven and healed you. Maybe you don't see any signs of harm done by your drinking back then.
The sad fact is, though, that often our sins against those close to us just fester deep down in their hearts and souls... and it can take a LOT to even uncover it, because they've tried for years to smother the pain with assurances of love, with duty, with 'forgiveness'. And once it's uncovered, it can take years and years to heal, while the person who caused it has moved on, has changed and has trouble with the fact that they keep getting dragged back into the consequences of old sins committed by someone they hardly recognise as themselves.
I'm not saying you're entirely to blame for the problems in your marriage - God forbid!!! More that you were two damaged, hurting kids who got married, found your own personal ways of dealing with your pain... and hurt each other unintentionally all the time. And now the obvious fallout is happening.
