I'm not sure whether I'm looking for advice, or just wanting to vent some stress, apologies if its long-winded.
I am pretty sociable, but I am naturally very introverted. More importantly to me, I often need to "charge" my social battery alone at home at times, especially when I'm overwhelmed or stress. I am ok with hosting parties if I have the mental preparation, and I am better depending on who it is. I am basically the polar opposite of my FH's complete family; they are very Type A and want to share everything and are pretty centric around spending time together. Which is wonderful, they are warm and I couldn't ask for a better in-law family, but it has caused some hiccups because they do not understand my social anxieties. I did not adjust well to family members (and old friends of my FH's too) showing up unannounced at times, and my FH and I did butt heads about that in general. I have been able to compromise on some of that, but we have generally agreed that my alone space/time at the house is my biggest comfort and need to maintain balance.
FFIL lives in Deep Creek (~3.5hrs away), and several times a year will come down to visit everyone, especially around the holidays. Our house was built by my FH's grandparents and is technically in FFIL's name, but we are renting it to own it fully soon. And with that fact, we always kept the guest room available for when he comes down. I do get a little claustrophobic but as long as we know specifically what dates he will be in town, I can be ok and not feel as overwhelmed.
So its been in the back of my head for a little while, because I knew that this would most likely happen right before the wedding. And I was really trying to prepare. But since we hit the 2 week countdown, I have become increasingly stressed out and just mentally exhausted by everything that needs to get done. And desperately needed my house (my "safe space") to decompress. I also have kept to a pretty consistent home work out schedule, which I have to do privately (I don't know, I feel so so weird working out with anyone watching). I knew that it was guaranteed that his father would come down and stay with us, but I wouldn't know how long. I was a little afraid to initiate conversation because in the past we have never ever tried to question any length of stay, because its family. And I knew it might turn into an awkward conversation.
Today, FH called me today while at work to chat and catch up on phone calls he's had with his family. His sister had recently moved, so I was told that FFIL was going to go see the new house, and come down to our house next Monday, to stay through our wedding that Friday. I hadn't really expected that long of a stay, I was ok with Wednesday or Thursday, but being there the entire week before our wedding kind of sent my anxiety over the edge. I said that I was afraid that that'd be too early, and pointed out that I was really getting stressed out and needed solo time at the house to decompress with my anxieties. I also emphasized multiple times that I know his FFIL is very self-sufficient and doesn't really need any hosting or entertaining, but it would still make me feel overwhelmed with having a guest stay at the house that long. As expected, he got upset and hurt, saying that its not like we're actually hosting anyone, and he couldn't understand why it would be a problem. He also said at one point, that was he to call his father back and tell him he's not welcome to stay at the house, which made me feel like the biggest asshole.
I know there are brides that do have family that stay at their house before the wedding to help, and I really wish I could be that open, but I just feel so overwhelmed and anxious with the thought. FH called back and asked what day would be more comfortable for me, and I said Wednesday or Thursday. I could only apologize about how I felt, but I could tell he was deeply disappointed. And I really feel so bad because his family is sweet and I want to be able to accomodate FFIL, but I am already having panic attacks at work and count down the minutes before I can come back home to my bubble.
I know not everyone can relate to this, but was wondering some other takes and perspectives. I know I will always struggle with my social anxiety and need for certain boundaries, and I'm always looking to compromise, but this time I just don't know if I can spread my mental energy that thin.
TL;DR: My FFIL wants to stay at our house more days than my social anxiety had planned for, and I just want to vent.
