My husband wont call or write me why would he not contact me

Every inmate does their time differently. If he is staying silent now it is probably his defense mechanism. You are probably going to have to give him some time. Whatever happened that caused his incarceration, he is going through some emotional swings especially if this is recent. He will go through several stages before he is able to actually confront his demons.

He might be blaming you (not your fault, don't let this upset you), but it is more likely a technique to keep you off balance so that he still maintains some sort of control over you. While he's locked up, he knows he cannot control your environment, what you do everyday, who you see (jealously is a huge factor). Not talking to you is his way of controlling this situation in the only way he can.
