Traveling Husband

I don't know if this is the appropriate group to post this, if not I will move the post.

My husband is currently in the process of getting a different job, this job requires him to go stay off several nights various times for training, classes etc. He isn't gone for a long period of time but I already miss him so much and I'm not used to being home by myself. We have two dogs so I don't feel completely alone, but it still isn't the same as him being here. If I sound like a baby, I apologize in advanced. I'm pregnant so my hormones have been flying ever since he left earlier today, any tips from any women who have gone through this with their SO?
