Beside myself

My bf of over 2 yrs and I have been living together for one. I am having a hard time dealing with him being gone for 10 days at a time!! I rode with him for a long time but now I can't! My children are grown.

I don't have a lot to occupy me while he is away! I moved from another state to be with him. Is anyone else in this similar situation? How do you handle it?
