Books similar to Bridget Jones?

I thought 'the wrong knickers' was good by Bryony Gordon

It was written in a different period but I think Diary of a Provincial Lady has similarities with Bridget Jones. The self deprecating humour, anyway.

It's all in the title!!! www.tripfiction.com/novel-set-in-ww2-london-a-former-bridget-jones-perhaps/ Dear Mrs Bird is WW2 equivalent (I think, anyway...)

I was going to say Diary of a Provincial Lady - for after Bridget Jones gets her man, has two children and finds Mr Darcy has retreated behind his newspaper and she’s left trying and failing to impress the neighbours and manage the kids (with only a cook and a maid to ease her burden )

A bit different but The Sober Diaries by Claire Pooley

Rachel's Holiday by Marian Keyes

Letters rather than a diary, but try Nina Stibbe's Love Nina. Another vote for the Provincial Lady. Letters again and also older, but Joyce Dennys' Henrietta's War might also appeal. More letters but Jill Tweedie's Letters from a Faint-Hearted Feminist is also well worth a try.

Hens Dancing and sequel Summertime by Raffaella Barker both in diary format.
