But Seek First the Kingdom of God and His Righteousness

Dear Savvy, I feel as everything is going against me, anything new is very hard for me to understand. My husband had his hours cut at work and now we owe everyone and I am being sued by the credit card companies. There just does not seem to be enough and I am trying to keep faith in God. I have been having lustful thoughts about another man. I don’t know why, because I love my husband and I love being in a family. When I read the Bible sinful thoughts go through my head as if the devil is trying to keep me from God. How do I handle this? I do not want to stray from God but these temptations are strong I have been having thoughts of doing things that I should not do to get money to pay bills. I need help. I feel dirty what can I do?
