Lord let this woman realize this man is in love with someone else, the fact he talks to her about his girlfriend is
for her to take the hint to lay off him. How would she like it if another woman do that to her if she had a boyfriend of her own? Help her put herself in the shoes of the other woman. Take out of her heart whatever she is feeling for this man if it is lust, or some other kind of emotions that she think is love. Send her a free good man her way for her to love, one without any relationships with another person. Come into her heart and fill the void she is feeling with your love and peace. I pray this in Jesus loving name, amen.
