Break up??

Hello! I was with a boy for 3 months..we were great together and he really cared about me and was always honest. I also had strong feelings .A few weeks ago he started having job problems and hes was tired and nervous. Then hisfather had a health problem not very serious..and he totally isolated himself...i sent him a message telling him that i will support him and he told me that he really cares about me and misses me but he feels depressed and doesnt want to communicate with anyone...I told him to relax and that everything will be ok..It has been 1 week since then and no contact.. I sent him another message today just to tell him that I hope he is fine but he hasnt read it..he hasnt been online since last week that we talked...I worry about him but also I feel sad and I miss him because I think that we have broken up..that we will never talk again.. I really want to be by his side but he doesnt want to i guess and we havent been together for a lonng time so I am afraid it will be easy for him to push me away from his life..What can I do?
