good signs, bad signs, or nothing at all

Took S12 to his baseball game, but the other team had cancelled without telling anyone. S12 wanted to go back to W parents, which put me in a really uncomfortable situation. I love her family, knew them before we started dating. I decided I would stick around for about 30 minutes to visit with them. I felt really uncomfortable, not because of them, but because I wondered how W felt about it. When I told them I made my excape I thought MIL was going to start crying. How would I know if wife wanted me to stay or not? Did I miss read her telling S12 to have me bring him back out as her way of saying she wanted me there, and then I blew it by leaving too soon? What are the boundaries with in-laws? My BIL wants to take me golfing, something we have done many times in the past. He was also my best friend in high school. Can I do stuff with them as long as I don't talk about W, or are they off limits? Am I just thinking too much about this stuff? Should I talk to her about her expectations with interactions between me and her family?
