Don't spend your time wondering what he is thinking or thought. I did that for a long long time and it got me know where. Just be happy that you did some good GAL'ing, had a good time even though H wasn't there. Yes you thought of him while there, but that's okay that will happen for a while. Its only natural. Glad you had a good time!
I went to a party a while ago and had the same thoughts. But hey we were there for our children and that's all that matters. If it did bother H, then maybe next time he will pay more attention to what is going on your lives. Be patient.
