Do I Get a Plus One?

Hi friends! I’m seeking advice from experienced individuals (aka all of you beautiful engaged/married ladies 😘)

I was recently invited to my childhood friend’s wedding. I haven’t kept in touch with her for years, but since we’ve known each other for our entire lives, I wasn’t surprised that she extended invites to our close-knit friend group from high school.

She’s having a more private ceremony with only family, and then inviting everyone to their reception. My hometown (where she still lives) is a really rural area, and she’s planning the festivities at her house, which is surrounded by acres of land (she has horses, so it’s a big property).

The wedding is in June, and I received the Save the Date in December/January. I haven’t received an official invitation but knowing the bride’s style and personality, I wouldn’t be surprised if they skip the more formal invite and just stick with the casual Save the Date.

My question is, is it rude to wonder about a plus one and if not, how do I ask? I was kinda waiting for an official invite since usually that will indicate if you’re allowed a plus one, but I don’t wanna wait too long and still be in this predicament a week before the wedding. I imagine it’ll be a potluck style reception with home-cooked food from the bride and grooms families and Im guessing it’ll be outside, so theoretically I wouldn’t be causing a seating or food issue by bringing my boyfriend? But I also understand that if everyone there had this thought process, the party could get out of control real quick.

Obviously I’m going to go to the reception regardless and I won’t be upset at all if she refuses, but if it’s an option and not a big deal, I would prefer a travel buddy and a built-in companion all night. What are your thoughts?
