Missing my Husband

So I am sitting here it is 11:20pm....I am really exhausted....but I just can't sleep. I really haven't been sleeping good at all for the last couple of weeks....my husband left for work on Jan 21st....and its hard...you would think I would be used to it by now....its not the first and def won't be the last time! But it really does not get easier. As the girls get older, it really gets harder....they understand more and express how sad they are that he is not here with them....and that alone breaks my heart. But I really have been trying to keep myself busy with working on our house, trying to get it ready to sell....with painting and what not....and it really has worked making things go by faster!
