Ex cried when he kissed me and said goodbye

My now ex boyfriend broke up with me over the weekend and I was really upset, being that it completely took me by surprise and that I didn't want it to be over for us. He said he wants to do things on his own and he is ready to commit himself completely to me. He said he wants to be with me, marry me, have kids with me, but he needs to work on himself before doing that. Than when we gave each other our last kiss, I cried and he cried also. I'm still extremely hurt over it and I'm trying to stay strong, but I can't stop thinking about that day. It was possibly one of the worst days in my life because I love him so much,

what does this whole situation mean? Should I move on? Keep my heart open for him? Should I call/text him? What do I do?

I do want him back, but only if he wants to and feels like he is ready
