I think if they r really your best friends and it is important to u that they are staanding next to u, u should have 1 on 1 talks with them and find out what the issues r. If u get them in a group they may be defensive or not tel lu the truth. If u still don't get an acceptable answer u should drop them and move on. This day is about u and FI and that is what u should focus on. Good luck and hugs to u. hope it all work out the way u want it to.
