My husband doesn't even talk to me now. I don't answer his calls or return messages. What should I do?

There are two possibilities: one is that his feelings for you have faded, and the other is that you have done something to make him ignore you. You can recall whether there is such a thing. I guess you are the second. What do you want her to believe you? In short, if it's really okay, your husband will believe you. Just stick to it.
