OG - typical scenario. Single mum meets chap, have a few dates; he is very kind, considerate and shows a lot of interest in single mum. Everyone likes him - including her kids.
After a while he confesses he has been convicted for the offence - but he didn't do it! It was her word against his and the child's mother put her up to it because........(any old excuse would do).
It's ruined his life, blah blah blah, single mum is the only person in the whole wide world he can trust and he loves her ......
