Just wanted to let you know that we're in the same boat too, and you're welcome to PM anytime while your husband is away.
My husband was put on alert a couple of months ago, but we finally got a definite date of mid July. Somehow it makes me feel better actually having a date, since it seems like our whole lives were put on hold while we were waiting for news.
Your husband's unit will probably have a "family readiness" meeting for all the wives and families to go over paperwork, emergency procedures, etc. before he leaves. That's a good time to meet some of the other wives and exchange phone numbers and emails. We had our meeting last month and that's what we did. It made me feel better to know I had someone else to contact in case I have any questions or just want to talk to someone in the same situation while he's away...
Hope this helps, and again, feel free to PM anytime!
