Am i being an overly sensitive baby?? lol

Hi guys! We’re currently getting our RSVP’s back and we’ve had a fair amount of “no’s”. I would say a good 75% of my fiancé’s family has checked off no. It’s probably due to the stress I’m under, but I’m finding myself to be a little offended when someone says that they can’t come 😂 I KNOW everyone is busy, and has lives, and I KNOW I can’t expect everyone to drop everything for the wedding. And the rational person in me also knows that weddings are SUPER expensive to attend.... but yet, I do get a little sad & mad when I see a no. Anyone else feeling this or am I just crazy?? LOL.
