I read this as a teenager and I have been looking for it since.

I believe it is set in Texas. He was the Ranch manager on her father's ranch. I know that is a basic plot for a western romance. But in this story she either runs away and gets abducted by outlaws or she was out riding when it happen. He rescues her, they spend the night in a cave. They have sex and then on the way home...it took a couple of days to get back. For some reason that i cant remember he leaves for a year or two when he comes back he finds out he left her pregnant. brothers beat him up at one point. Any way i know this is [retty gerneralized but if it sounds famiar to any one let me know.

Thanks!

Sounds like a good book, but I'm drawing a blank.  Sorry.

You might want to check out Snow Bride by Dallas Schultz.  This isn't the book you're looking for, but it has a similar theme - hero is ranch manager, hero and her brother get in to a fight, she gets pregnant, etc.  I thought it was a great read. 

That almost sounds like an older Sandra Brown book.
