I'm not 100% on your sitch but couldn't help but notice some recent similarities.
My H was gone to us and pretty absent in the first few months.
Then he started reaching out about things we used to talk about. I ignored it because I didnt want him to cake eat. I still didn't have the DB thing down.
Anyway when the boys started basketball where we had to be around each other a couple hours a week I started to experiment. I would smile at him from across the court (this was about a month in) before that I kind of let him take the lead but I was fun laughed and had a good one and so did he. Then I experimented with not engaging - he was an a*s!!
Who knows what this is from your H. It may be nothing or there may be trouble in paradise and he's seeing if you're receptive to him being friendly. Just thought I would play Devils advocate a little
