Hiding in bedroom because we have guests :-(

Here's the pickle I've put myself in.

My husband has guests every Monday night for board gaming. They game in my living room. Once upon a time (months ago) I decided to stay in my master bedroom during the game nights, because of, you know, social anxiety.

It has escalated, in that we've had dozens of guests over whom I've never even met, even though I've been in the adjacent room through all those game nights. They've occasionally even asked about me (they know I'm home) and my husband has told them I'm busy. I have been busy with school work, but not THAT busy...

At this point, I'd love to be able to go into my own living room during Monday nights, but feel too awkward about it after such a long time of hiding! And I feel so ridiculous about all of this.

Sometimes I sit here and cry because I'm LONELY and there they are, laughing and having fun, basically under my nose, week after week, month after month.

I'd even want to join them but I have a HUGE reluctance to "butting in". It's just my husband and almost always guys, and I wouldn't want to be the one girl who ruins it for any of them.

I guess I just need help with this. I feel a bit caged in!
