Congratulations on being sober for 7 months!!!!!!
Pat yourself on your back.
I agree with the others about your kids paying for their own car insurance and cell phones and doing their own laundry when you get down to real life stuff.
I am not a parent so I throw this out to you:
You are the parent so you have rules for them to follow.
If you want to live here then obey the rules.
That is how I grew up.
I worked so I could buy myself clothes for school.
When you turn 18 you can leave.
I would encourage you to check out meet up groups. Find some out side activities that you would enjoy or rekindle. Maybe your church if you attend would have a mens group???
As far as your wife goes. Only you have the ability for change.
You could ask her to go to marriage counseling if you want your marriage to be different.
Maybe it is time for a romantic vacation weekend get away????
I feel for you.
