Paula, Paula the more you tell us about Tim, I can tell you he is a loser and you will become just like him if you keep seeking after him. Please Dear Sister in Christ open up your eyes and see that the best thing that has happened to you is him walking out on you.
Lord enlighten Paula and show her the way to you as you give her peace and strength to start anew. Fix her relationship with her twins and help her financially, but not for her to give it to Tim. I pray this in Jesus name, amen.
