Maybe there are other DCs?
The thing is there is a classic scenario. Once you challenge, he will deny, lie & deflect, or finally play the "remorse card", & give you a shed load of apologies, & promises to never do it again, in between blaming it , at least partially, on you, because, you nag, don't listen, get things mixed up, (this is the PA classic) & accuse you of meddling & snooping...
at which point you will feel obliged to defend your actions & get embroiled defending yourself.
You need to be ready for this trap.
If you challenge, could you get a family member present ?
1).You tell him you know that, say as an example: the mortgage hasn't been paid, & you are living in fear of losing your home. He has been lying about paying
2.), He will deflect, that he hasn't recieved the reminders, then attack re snooping.
3) You defend yourself, he throws a tantrum, & you end up doubting yourself.
alternative 3) *This is not working for me, living with a pathological liar & the continual lack of respect is not an option. You are leaving.
detach, & do NOT defend or justify, Don't get drawn in, Just say NO,
as you know, "NO" is a whole sentence.
