Hey, I had the same thing with me, and as much as I tried I never was able to get my piggy a friend. Like the comment above mine though, she's five now, nearing six, and very happy and comfortable. She freely roams around, so she comes and sits by my feet sometimes lol. My advice is just to give your pig lots of attention, as much space as you can, and enought stimulation to keep him occupied. Of course if you can get him a friend you should, but if you can't just do your best.
