My DH's ex wife had a baby girl last summer. We are expecting a girl in April. She has never been amicable....in fact, she has always been down right mean to me and DH. I am not completely innocent because after Thanksgiving I defended myself with very harsh words. Anyway, she sent a trash bag full of baby clothes. I am so thankful...they are very cute and much needed; however, I am overwhelmed with bitterness because I have trouble excepting anything from her. DH laughs and says" Be the bigger person and write her a thank you note!"
What in proper etiquette in this situation?
