then she got mad and said these hurtful things about me and my husband and said we are fake Christians. I’m not sure what to do in this predicament. I’m so heartbroken she would say such horrible things. I would post but I’m afraid it would be to long for anyone to read and not give me any advice as to what I should do now 😥 Here is a little bit of what she said to me and my husband.
