<human>: Condense the text into a few key points

We've been together for 4 years, living together for 1. 

I'm an introvert and like time alone. At work I am constantly dealing with people, which is stressful for me. On weekends we'll go out to shop for our upcoming wedding, or spend time with one of our families, or hang out with her friends. I very rarely get to have any time to myself. 

This weekend she's inviting her bridesmaids over to do some wedding planning. They're bringing their husbands over and it's just expected that I want to entertain them when really I don't care for them. She approaches this like it's a play date. 

Anyway, not wanting to entertain is no secret to her... in fact she told me "You're going to have to be on tomorrow," jokingly but she knows how I'd rather spend my one day off. I feel like it's really inconsiderate, and when I told her that I was frustrated that these guys are coming, she got angry with me. 

Eventually she apologized for making me play host. She said that it's been a few months since we had company and she wants to talk wedding plans with her friends... which is so far from the point of why I'm frustrated.
<bot>: Fiancee is very social. I'm very not. She's angry with me because I don't like getting together with other couples and entertaining "the boys". How do you deal with a difference in social needs?
