I thought I was reading my sister’s story when I read your post.
She was married to a gambling addict who ripped through the kids’ college funds among other accounts. She found out when an armed guard showed up at her door wanting to know about payments. She almost lost her job over all of it.
She divorced the bastard but had to pay him a huge amount of money just to get him to go away - 1/2 of a million dollar home that SHE had paid for. He tried to go after her retirement but she managed to block that through the use of a VERY high-priced lawyer who threatened to turn over ex-s thefts to the police for prosecution.
She said it set her back financially about 10 years after the dust finally settled.
A few months later, she got a call from LifeLock that her ex was still trying to open credit cards in her name.
Yikes! My ex had issues with pain pills post-surgery and it escalated from there. Rehab & marriage counseling didn’t stick; he was just phoning it in.
Mine found a new ‘mark’ as soon as the ink was dry on our divorce papers, proving that some women consider ‘Prince Charming’ to be a broke bum with no prospects, addicted to Oxy and losing his teeth due to the abuse of opiates.
In his (minor) defense - he didn’t start out that way - but he also wasn’t interested in getting better, either.
Took me 5 years to rebuild, financially. But, things are OK now. Prayers up for your Dear Sister. :)
