Husband wanting space and seperation

So me and my husband have been married for 10 years. Through out these 10 years we have dealt with drug abuse on his side. It was a rough time but I stuck by his side. He finally decided to do a long term rehab. In general it worked successfully. He came out a whole different man. I loved it. He showed me so much love. The love I was craving for so long. In his return he stayed with his mom and I stayed with mine. Now we share a daughter together so I always try to make sure we all spent enough time together. But with him staying at his moms it made it a little difficult. His mom and him finally had a falling out and he decided to move out. At one point he was ready for us all to move back in. After a certain time, he started drifting away. His affections slowly started fading off. He finally reached the point of saying, I’m not ready mentally for marriage and family. He wants us to stay at my moms like before and just come over on the weekends. Let him work all through the week. Now my reaction is, that’s selfish of him. I reacted very negatively to this. I was pointing fingers and accusing everything I could in the book. Well a month goes by and tension is even thicker. He keeps telling me some of the things that he learned in rehab is he has to find himself in order to be a better man and father to us. Of course my first thought was, what a load of crap. But the other day it all came to a head. We had an explosive argument. He wanted me out. I felt hurt and heart broken. But I packed mine and our child’s essentials and left. But I’m sitting her at my moms thinking what happened. Did I not listen to his needs and wants? Was I rushing into things thinking that’s what he owed us? I know everything that happened with his addiction is not my fault. But what did I not do to help his sobriety in the long run. I’m just curious is their any other wives who have dealt with this? Did a temporary separation help your marriage? I don’t want to divorce him. I still miss him tremendously and it’s only been a couple of days.
