My husband was out of town for work recently, and it made me bummed out. I had no one to talk to or spend time with. 
That sucks. Maybe you can find yourself a new hobby that will keep you occupied while he's gone?
I mostly just have been baking and reading, relaxing and just having some me time, but I just miss him haha. 
That's understandable. I'd probably feel the same way in the same situation.
