DHs ex 'took him to the cleaners' or rather he just let her have everything without a fight. She got the (his) house with 6 yrs left on the mortgage, which he paid for 2 more years. The car. The dog. The friends and the pitying looks. She also 'got' DSD and a decent amount of maintenance (more than CSA).
DH got two bin liners with all his clothes in and a photo album.
When he left the Army 6 years later she also wanted half his gratuity and his pension. Thankfully by then he'd met me and I pointed out that 1 - she wasn't entitled to half and 2 - what she'd had when they split was over double (in monetary terms) what she would have been entitled to.
DH pointing this out was enough for her to tell everyone that he'd left her destitute, screwed her over, didn't give her any money, neglected his child and so on.
If I had met him at that point I may well have believed her, thankfully by then I knew exactly what she was like and whilst DH wouldn't stick up for himself I was extremely vocal about the bollocks she was spouting. Eventually she stopped, but not before she lost all the friends she'd 'gained' during the divorce.
So yes, there are women out there that do it 'just because they can'. There isnt always a reason.
