Planning a wedding in 2 months

If I was you I would as politely as possible explain that the ceremony will be very small with only family and close friends. People will understand! I would also consider putting a privacy setting on certain parts of your wedding website. Dates, times, location etc.. otherwise people might just show up! Good luck!

Not at all! This is your and FH decision and they should understand that you want a small wedding. Good luck.

Emily said it best

Kind of a harsh truth but 2 months with terminal cancer is not guaranteed. My SIL's father had terminal cancer after her and my brother were engaged. Doctors gave him 6 weeks to 6 months left and he passed away after only 1 week. They had a very private ceremony with her parents and sister and then had their wedding they had initially planned for later in the year.

I also want to stress that the doctors are not always right. My mom was given 6 months to 1 year, and was gone in 5 weeks, so the earlier the better for your ceremony, if you can do it. Good luck to you, and I am so sorry for what your family is going through.

Personally i think it is rude of people to ask about a wedding before they have been invited! One should never assume they're getting an invite, no matter how close they are, until they get one. I am sorry you are now in the awkward position of having to tell them but @Emily made a great suggestion -- politely tell them the ceremony is going to be small and intimate, but thank them for their well wishes.

Perhaps set privacy settings on the wedding website too, now that you've gotten the initial joy of showing it off out of the way. That way only people you invite will see it moving forward.

PS: so sorry about FMIL, wishing you all the best and good luck with the planning.

Don't tell anyone anything. Stop posting. Plan something small and very private and as soon as you can, and thank everyone for their good thoughts.
