Cancer man ignoring me, advice please?

[Mama Krabs]

Well you cannot pry him out of his shell that is for sure. A bit of tenderness and reassurance and you can get him to talk to you again. Also, even though we hate confrontation, you should see him face to face. Remind him that there is nothing to worry about, Cancers are very emotional and we are very humble, too humble at times. Give him a week or so, let him think it through and then confront him about what is wrong and simply talking it out and understanding will save what you have.
