This movie was an 80's patrick swayze movie where he met a girl who was in boarding school somewhere in the mountains and the fall in love... he sneaks her out and sneaks in the school... game wardens or feds or govt are after them and trap them near a cliff w/ a running river below and swayze looks at her and says "do you trust me" and then they grab hands and jump... that's about all I can remember... thanks

Sounds like Fire with Fire (1986) (http://www.imdb.com/title/tt0091053/) with Craig Sheffer.
