I made a decision to add my fiance's sister as a junior bridesmaid, months after picking my bridal party. Originally I didn't want to. I debated literally for months. Part of me really wanted to, knowing how special it would be not just for me but for her. The other part of me did feel a sense of obligation. My fiance told me he has no feelings either way. I didn't want to start a marriage with any potential negative energy. I knew that if I didn't pick her to be in it would be something that caused tension between myself and my MIL. Who made it clear she wanted her daughter to be in the wedding. However, it's something she would never outright say to me that she was upset about but it would linger. And I don't want that. I don't want the negative energy or anything held over my head. But I really don't like the feeling of it being an obligation. I just can't shake this feeling I have.
So I asked her and she was happy, and I was happy that she's happy which is great.
