This woman just lost her husband and most likely had to see him at his worst. So feeling slighted should be the last thing on your mind. It seems a bit self-centered doesn’t it? This woman no longer has a companion to share her life with. She now has to rely on others to feel like she belongs. I think that last thing you should be concerned about is any slight she may have caused you. I think if you have some compassion and empathy now is the time it should be kicking in. Think about the loss of your husband and all it would mean. Be loving and kind to her. It will say more about you, will impress your husband and more importantly you will impress yourself.
