Yes, the party was in our home. I often struggle with feeling bad or wrong for whatever I'm feeling on top of all the crap that comes with being hurt. It's also something I know about and work on, but I guess it leaks out a bit still.
After more talking yesterday, I went ahead and opened a dialog with K about what happened. She's very new to all of this, which I should have included in my original message. I think not being honest with her about what happened was making me feel guilty as well.
Silver lining, I'm glad the situation brought me to this forum and look forward to being active here. Seems like a really great group of people!
