I'm quite interested to know how people handle this. I remember that when I first got engaged there was a lot of excitement and such, but after like one good day that excitement died down, and you realize that no one actually seems to care about how your wedding planning goes.
I would like to think that for the most part I handle this pretty well, and try not to take it too personally. Sometimes I might offhandedly mention what I've been doing wedding planning wise, but unfortunately the farthest that conversation will take me is a, "Oh that's cool". It sucks, but I'm used to it now.
I like to think it stems from the fact that majority of my friends are either single, or are nowhere near to making that life-long commitment with their partners, so I try to understand their take on things.
I won't lie, sometimes it hurts, I remember I went to my venue yesterday, and thought it would be fun to post mini-videos of the venue on the group chat, but no one even bothered replying, so I'm not gonna lie that I felt a little down afterwards.
However, on the off chance someone calls me to ask me a question about it, or gives me some criticism regarding how I plan it and what I decide to do is actually pretty nice. For example, I went to eat out with a bridesmaid the other day to talk about wedding details, and even though she spent a good thirty minutes angry that I won't be having a fancy full bar with cocktails, and just having beer and wine. I'm gonna be honest that I was just pretty elated the entire time she was giving me an earful, since it'd been so long since I've had someone that wasn't my fiancee give me their opinions when it came to anything wedding related.
