How do you think a person should react in this situation?

So me and my husband are supposed to be temporarily separated. He currently lives with his mom and I live in our home with our two kids. Thing is, he is always at our house with us but then at night he goes back to his mom's house. Now don't get me wrong, I wanted to be separated for a while but it's starting to wear on me that he gets to come home all day then go somewhere else at night. Sort of like a have your cake and eat it too thing. On the plus side we used to never kiss but we smooch now when he is leaving. We used to never say I love you but we do now. but when he is gone to his mom's house he seldom calls me at night and he shows no interest in coming back home. It's been a month since we have been separated and I told him I missed him and he said he missed me also but he didn't say he wanted to come home. He is normally emotionless but I don't know whats going to happen from here. What do you think?
