My wife's brother and his fiance arrived today and my family were very excited. They hadn't been here since our wedding so all three kids have grown a lot in that time. I enjoyed the time spent with everyone catching up with one another. My wife's sister and her daughters arrived in mid-afternoon and I started to feel like a fish out of water. All of the adults know about our separation and I stayed clear of my wife meaning I stayed clear of everyone else too. The kids were having fun and I really didn't know what to do with myself. I considered going for a walk or drive. I felt awkward about just up and leaving so I stayed and watched TV in the other room.
On top of that, my BIL's fiance is pregnant. I haven't actually been told, I just overheard the conversation and commotion in the other room. I felt that it would be rude to just butt in and congratulate them when they haven't told me and my wife was really excited so I let them enjoy it as a family moment and I'll have a word with them tomorrow to offer my congratulations.
