Walk of Shame?

I haven't really mentioned much about my living situation on this blog. But I am tired of keeping quiet, besides I am leaving this month and you guys don't know the people involved, anyway.

I live with a very sweet couple that are in their 60's. It started out as a temporary place to live when I first arrived in town and I ended up staying. They cook for me, they do the laundry, it's a lot like living with your parents (except my parents would expect me to do laundry). Granted, it has not allowed for much of a social life, but I've coped and just thought of it as a temporary situation. In January, Chris met me at the airport with news. He informed me that he was leaving Jenny for another woman. It seems that she works at my school and they have been sneaking around town for the last few months. After that, I started to spend more and more time in my bedroom, leaving more room in the house for Chris and Jenny to sort out their business. It was a very awkward first few months and now I guess I am just used to it all. Chris and Jenny have sold their house and we will all go in different directions at the end of the month. Jenny has spent a lot of time away, visiting her children/grandchildren. While she has been gone, the new woman has been spending more and more time here. Okay, fine, the marriage is over, but this is still a bit awkward for me. Anyway, this morning I woke up, had my cup of coffee and was surprised to find the new woman entering the kitchen to make her morning cup of Joe, too. Am I a prude? Isn't this crossing a line?!
