Feeling guilty!

L
Tomorrow my boyfriend and I are going to a housewarming barbecue for some close friends of his. We just went to their wedding a few months ago and they found out they were pregnant around the same time we did except she miscarried early. I'm worried that people are gonna be congratulating us and talking about our baby etc in front of her and make her sad. I'm gonna try to avoid talking about it just so it doesn't hurt her feelings but I know it'll be talked about either way. How should I handle this?? I feel terrible! 🙁
