She may be afraid. She is afraid of her future, afraid of how she will live without her husband, afraid she will make a mistake, afraid she will not know what to do, afraid she will be taken advantage of. Be gentle and kind in your approach towards her with integrity.
She should not be stereotyped. If she has a fresh manicure and Starbucks cup in her hand, don't assume she is not managing her money well. Thank God for provision and care for her in ways beyond immediate needs, without judgment.
She needs hope. A few words of hope are invaluable. Affirm that God is there even though you may not know how He will be there to meet her needs. Take time to pray with and for her.
She is created in the image of God, therefore has immeasurable worth and value. Treat her accordingly in every respect.
