In Limbo!?

[Hurtinky]

I have been married 29 years. High school sweethearts! We have 3 children; 2 daughters, 1 son. 17, 22 and 26. Three months ago, my husband was talking on his cell phone for an hour and half one evening (he normally used the cell phone for 10 minutes for the whole month!) After asking him about the number on there and who it was, he said it was someone he had dated a couple of times right before we got married. She lives 1200 miles away, he found her on the internet and contacted her to see how she was! Said it was no big deal. I said it was and that we needed to talk about it. He said, No what we need to talk about is being seperated! Before the next two days were over. He told our three children (when I wasn't around) that we were talking about getting divorced!! I was devastated! He says he wants to keep things "normal" until our youngest graduates from high school (2010). He moved out of our house and into his parents spare room about 3 weeks later. He talked to the woman 3 or 4 more times and I believe that is done now. We are in LIMBO!!!!! He says he really has no current plans. His entire family has stopped talking to me and haven't had any contact with our kids for this entire time. I don't know how to handle this. Please help!
