The whole world seems empty

"When one person is missing, the whole world seems empty."
This was in a book I read to the kids tonight, and it hit me like a truck. This is the feeling. This is what goes through my head every minute of every day. Life is empty without Mike. Don't get me wrong, I am making a point to live life to the fullest now, because this has reminded me of how special and precious our lives are. But my life is still empty. Everything seems to have less meaning and be so much more temporary. Yes, I have our kids to keep me going and living. Yes, I have our families and friends around us keeping us afloat. Yes, I go out and have fun with lots of people and celebrate life the only way I know how - by living it. Our daily lives go on, but he's not here to share anything with. Not here for a quick text with an 'I love you' in the middle of the day. Not here to call with something funny that happened at work. Not here to sit down with at the end of the day and unwind, drink a beer, and relax together - reminding each other of how lucky we are and what good lives we really do have. And how much we appreciate each other. Not even here to fight with. The person I shared my world with is gone. My world is empty right now.
For some reason the past couple of weeks have been particularly hard. Work has been busy. I've needed more help with the kids. It's been stressful. And the one person who I would come home to at the end of the day and talk to about all this is simply not here anymore. The person who supported me all these years, and who gave such great advice like "fuck all of them, who needs them!" isn't here to bring me back down to Earth with a big laugh and a reminder that I really shouldn't give so much of a shit all the time. The person who put up with me, not matter how crazy/bitchy/ridiculous. So I sit here and I write. I've even started bringing work home with me, to give me something to do and make me feel like I'm doing something constructive rather than sitting here doing nothing with no one to talk to (Mike would be so pissed at me!). I've got a couple of books to keep me company. But my world is empty. How did I not know? How was I so unaware of how important this person really was to me? I mean, I knew I loved him and I wanted to spend my life with him - but our marriage wasn't perfect and there were definitely some times we had wondered if maybe we'd be better off apart. I was so completely unaware of how deep my love for him ran. That without him my world would be empty. And it took this, of all things, to make me see it. And he's not even here now for me to tell him of this amazing revelation I've had. Because I know he'd laugh and say "I know. I told you so, Ab."
