Movie about deceptive couple on road trip

I remember watching a movie, american indie type movie definitely post 2000. It is about a couple, the man has dirty blonde hair and the woman looked like Laura Linney (although I can't find it on her filmography). In the first scene they seduce a young couple on their honeymoon, they meet at a restaurant and then eventually go back to the bedroom, but leave just before consumating, leaving the young couple confused. another scene involves a church and stealing the money and watching them accuse each other (I believe the minister was a black woman). at the end the woman drops the man off at a house, and it is implied he has a family and kid there. I have looked everywhere for this movie including using chatbots but have not been able to find it.
