I believe that they don't want to talk because they are confused with their own lives and directon. On one hand they like the freedom, not being told what to do, no pressure, but then they see the family, w, responsibilities and are torn.
Also the depression gets in the way and fogs the horizon. Sometimes they are paralyzed and can't even think straight or respond to anything.
Best advice I can give you is, let your h be and try to reconnect in small ways. All interactions need to be fun, loving and kind. No R talk. You need to cloud the vision for your h as to why he left.
For example, if he is enjoying your company so much and is not focused on all the faults of the m, he may one day say why did I leave this beautiful woman again.
Try that for a 180.
