Paula listen to God, he may want you to be still and learn while you are going through this, instead of feeling sorry for yourself, pick yourself up and do something with your life. Get a part time job to help you financially like so many women out there have to do today. Go to school at night, there are so many things out there to keep busy, clean and redecorate your home, go to the gym. That's your problem you have to much time on your hands after work so you start getting depress and feeling sorry for yourself. Be glad for your children for they seem to be doing well, that's a nother blessing to be grateful for. About Tim forget him he is a loser and will take you now where but straight to hell with him, like he has already done so much harm to you and your kids.
Lord continue to protect and help Paula also teach her your ways are not her ways, and give her wisdom. Give her the strength she needs to go on, and send her some godly friends. In Jesus name I pray amen.
