On one end, you have sitting at home, staring at walls- on the other end you have finding a new wife.
There's LOTS of stuff, in between.
I haven't been through what you have, and so I can only imagine how difficult and heartbreaking your situation is. I did get divorced, about ten years ago- she was the girl I wrote while I was a missionary. I fought for years to save my marriage. (In a weird way, I felt like losing my marriage would somehow invalidate all of the feelings and memories I had on my mission, and earlier, when we were happy and in love.) I was gutted when I knew it was over. But then, a while later, I met another girl, fell in love, and have a happy life with her, and our kids. Obviously, in my case, the marriage ended by choice. And unhappily. But I DO get feeling like you're never going to be happy again.
It doesn't sound like you're ready to find a new wife- right now. But that doesn't mean you can't enjoy female companionship. When I was newly divorced, I started hanging out with a great friend from my mission- in a purely platonic way. She was also newly divorced. It got me out of the house. I had fun. I did new things. I made other friends, and eventually, one of those new friends introduced me to the girl I married. All because of my friend, Katie.
I know people who have gotten married too soon, after a spouse's death, and those marriages ended in divorce. I also know people who were too afraid of being hurt again, or never finding love again, and regretted it.
Don't rush into anything- which doesn't sound like it's going to be a problem. But don't let fear motivate you either. God has a plan for you, of that, I am certain. In the meantime, find some good female friends, buddies you can have fun with, but not feel any pressure.
The most important thing, however, is that you go at life at the speed at which you are comfortable. Don't let anybody else pressure you to move faster than you feel good about.
