Dear Jojo
This lady may not be who she says she is. Very sick people prey on sympathetic such as yourself and have fun at their expense. If this lady is in the predicament you say she is, I would think it be best you urge her to seek help/advice from someone trusts.
You seem to be a God-fearing man, steadfastly pray for her, as you have repented for your sins. Ask the Father for strength and guidance, He will not forsake you. Then finally forgive yourself. We are imperfect beings and as long as we continually seek the grace and likeness of our Father, through His Son, we are making the effort to lead the life that is pleasing to Him.
God’s speed.
