Thicker than water

In the back of my mind I assumed that there could be problems down the road, but I never really knew exactly how things were going to play out. You see one of my roommates is cousins with my ex. Obviously this is how we met: my ex via my roomie/friend, not vice versa. I've tried being friends with my ex, but lets just say it's a work in progress.

I guess I have been feeling a bit awkward about it over the past few days: Ex visiting the apartment to stay with the roomie. In one sense I'm glad I have been at my parents place, partly to just remove myself from a potentially awkward situation, partly dealing with other life traumas. I totally understand how family is family and I'm not going to say, "I don't want X, Y or Z here," but I really wish I had talked to roomie about it before hand. I guess that's one more thing I need to do before New Years...
