Advise: relationship on edge.

Me and my ex boyfriend I guess you can c all him that have been going through a lot of things we lost the baby and it seemed like he distanced himself and we tried just focusing on us and getting us back to a good place and that happened. He asked was I ready to get married I said yes he said he was and then he drifted away again and now we aren't talking . I love him and I wanna be with him but  unsure of what to do!
