PCS orders

So my boyfriend just got projected PCS orders to Fort Campbell, Kentucky. Which really sucks because we are both military and I will be stationed here in Hawaii. Right now we are both in Hawaii but he will be leaving in a a couple of months. I really don't want him to go, him being here in Hawaii is the only thing that makes it worth being here. All my family is back in Wisconsin and I don't really have any friends here. I just don't know what to do. I know that all he has right now are projected orders and they can change at anytime but I highly doubt they will. This is the first relationship I have ever been in. Sorry for the rant I just have no one to talk to and when I talk about it with him I want to cry. I just don't know what to do.
