Calling all Austenites!!!

[Samantha]

I am looking for a Pride and Prejudice continuation. The only parts that I remember are Elizabeth having a miscarriage and Darcy getting mad at Elizabeth because he thinks she is having an affair with one of his friends/neighbors who is gay. His friend had confided in Elizabeth but wasn't comfortable telling Darcy. I tried looking through some of the lists on here and I have not had any luck! Please help!
