My FI and I have a bit of a dilemma. We are having a small wedding ceremony in Jamaica with only immediate family and best friends, followed by a bigger reception after we return home. We sent out invitations a few weeks ago for the ceremony. My FI does not like his step-mother at all, and she has caused a scene at family gatherings in the past, so he does not want her at the ceremony. When we mailed the invitation to his father, we addressed it to FI's father and half-sister, omitting his step-mother. (BTW, this was totally FI's decision.) It is noteworthy that FI's father and step-mother have been unhappily married for as long as I've known them (8 years). Tonight, FI's father called and said that this has caused somewhat of a disturbance at home and hinted that he wants us to send another invitation, addressed to all of them. FI told him that he does not want his step-mother at the wedding. FI is torn. Although we're pretty certain she gets the picture that FI doesn't want her there, he thinks she might come if we send another invite with her name on it. Because of her past behavior, FI wouldn't be surprised if she causes a bit of a scene if she comes to the wedding. What to do??
