Is there hope after he has you move out?

I need some advice on this. My now technichally ex and I were together for two years and living together for one. He proposed in February and in May we put off wedding plans due to fighting. About three weeks after that he tells me he needs his own space to figure things out and wants me to move out. I have some insecurity issues and they really upset him. That is what he says is the main reason for his unhappiness. He told me that he thinks we share many things in our hearts and personalities that can make our relationship work just not at this time. He has told me that he wants to feel in love with me again and that at some point he was pushed too far and fell out of love. He hopes that by spliting up he can get that feeling back and be able to communicate better with me about how he feels. For the last few months, maybe even our whole relationship, he has just focused on what makes me happy and never expressed his unhappiness fully until now. I have moved out and havent talked to him in 3 days. I am so missing him, way more than I even thought. It has been 3 weeks since the news and we have not talked much since he asked me to move out. I really tried to do anything I could to make it work while I was there but he wouldnt have it. He didnt want to snuggle much or share the "I love you" because he didnt want to get emotional. He cried alot and I can tell he is hurting. I want to believe that things will turn around. I just dont see how you go from wanting to marry someone to I need you to move out I need my own space. He has avoided me as much as he can. We didnt see eachother for over a week. We finally met eachother at the house to go over a few things and he looked really sad. He gave me a hug first and seemed like it was hard for him to not touch me and be near. Im heart broken and confussed! He only used the official words broken up once the rest of the time he would refer to it as separating or splitting up or needing time apart. I think that he has a lot of stress in his life right now that is making him unhappy in combination with our troubles. He also recently met his biological father for the first time and met his 3 siblings for the first time from him. He says that is not a stress factor in his life but I think it may be. He is a little emotily confused I think. I really could use a positive opinion on all of this.
