So my FI's friend was supposed to be one of our bridesmaids. She just told us she's pregnant and due 5 days after the wedding. We mutually agreed that travelling and being in the wedding would be too much that late in her pregnancy. I'm bummed that she can't be in it but I'm happy I have an open spot to ask a close friend of mine. How do I ask her without insulting her? I don't want her to think she's my second choice?
