If you were the second wife/new partner, how long was it before you realised the reasons why your partners previous relationship broke up wasn't because of her as he initially suggested (through snippets of information not the usual slagging off of the ex which I know is a red flag) but actually because of his abusive tendencies.
Mine has become apparent after 10 months but probably only because I had a much hotter radar than I would've if it hadn't been for my own abusive ex.
