Confused and looking for advice

[hockeymom12]

So today was a better day. H showed up 20 minutes earlier than he said he was going to, not trying to read into this but by doing this we saw each other. He brought the groceries so I thanked him nicely and we had very good 20 minutes together, just talking about nothing. When it was time for me to leave I said goodbye to him on the go and told him to have a nice time at his parent's as well I told him I would see him the next day at our daughter's sporting event. I took the time to say goodbye to the kids and left. H then called me at work as someone wanted to come see the house ASAP and he was not there, so I ran home quickly cleaned and went back to work. When H and the kids got back from his parent's they were locked out of the house (my fault) I thought he would be livid but he wasn't at all. He then called me at work again later on and said hi this is your husband (he has not said this since he left, he always uses his name), I did not react as I am not sure it means anything I just said hi, he then passed the phone to my son who was not happy to be with his father and wanted me to deal with their conflict. I did not get in the middle just told my son to go to bed if he wanted to be left alone.
