Hi you I seen this country music video a while back and can't remember the artist or the song. I know some of the lyrics and I remember the video. The singer is female

Its about a guy not leaving his wife like he was going to for this other girl. The girl he was supposed to leave his wife for sees him and his wife at dinner and sees that they are still wearing their rings. Then the girl runs into the bathroom and starts crying.

That's all I can remember but I loved the song.
Any ideas? :)
