Urgend Prayer Needed for my Marraige

My wife says she is going leave me. My ex wife is her hot button. With good reason, she has a lot of anger for my ex, who is a bitter, vindictive, hateful person. This morning, she inserted my ex into an argument that had nothing to do with her. I tried to pray a rushed prayer as she left for work, but with my ex on my mind, I accidentally called my wife by my ex's name in the prayer. She went ballistic. I slip up like this maybe 2 or 3 times a year, and she had threatened to leave next time I did it. I've never seen her this mad before, and she has been sending me angry texts saying that she is leaving, stating reasons. We're newlyweds and we've been under a major spiritual attack as we've been trying to make God the center or our lives. I'm scared to death she may actually follow through and leave. Please pray that God would change her heart and convict her to reconcile with me, stay with me, and honor our vows. Please pray for our protection, and for God's blessing on our marriage.
