I sent my husband lots of mail, a few pictures, but the DI's will look through them if they think that is what is in them. I was fortunate to be able to go and see him several times, and we talked alot on the phone. He had a few calling cards, but had his cell phone in his car. When my husband first left, there was no support here for me, and I didn't really get anything that he was about to go through, all I know is that I left him in P-cola, which was the hardest thing that I have ever done. Shortly after that I found this web site, and a few journals, that filled me in on alot of what was going on. It helped that I new some of the things that he would tell me about, and then other things I could ask him about. Find someone who is going through it, and talk with them. I started chatting with Hartmansgirl, and even though her OC was behind mine it helped to be able to chat with someone!!! My husband also got to know her OC, so it made a difference, it was not like we were in two different worlds anymore!! Our daughter drew pictures for her dad and I sent them, too.
Good luck, pm me if you need to chat!
