You could read almost all of Judith McNaught's historicals and they all have this theme. One of my favorites from JM is Something Wonderful. I really liked the h in this story and wanted to junk punch the H at times (many times) for being such a douche bag to her. He goes through various phases of not trusting her, but that last one... oh crap, when the h realizes what the H believed of her, you totally feel it rip your heart into shreds as it did hers. :'(
For contemporary, one of my other favorites from JM is Paradise. This one has misunderstandings on both the H and h's part.
Another great one is The Unwanted Wife by Natasha Anders. Great story where the H believed the h was in on the plan with her father to blackmail him into marriage. He finds out and when you find out how he treated her..... argh! Still loved it though
Hope you enjoy these stories as much as I did
Edited to add: Just remembered another one I really liked called Wanted by Her Lost Love by Maya Banks. The H believes his fiancee, the h, and his brother were cheating on him and kicks her out. I LOVED this one because the h says all the stuff you wanted all the other heroines to say (e.g. why didn't you trust me? i never lied to you, etc. stuff like that).
