Dear HCGLNS,
Ah the eternal paradox! We want so much to have time for ourselves and then we don't know what to do with it when we have it. I fell your pain in this one because I have no friends who live close by so I don't know what I'd do, either. I won't suggest playing games online although that is a viable option. If you are not averse, go see a movie - preferably one which you would not be able to see were she with you. No, I'm not talking porn. I'm talking about an action flick or something like that, or something that is to your taste but not to hers.
Go to a bookstore and just browse. Sit in a comfy chair, drink a latte and read.
If you have friends, go see if they want to do something. Go to a bar, see that movie or just hang out & watch sports yelling loudly at the TV.
If you like to paint, paint something. Do that hobby you've been putting off because it takes too much time away from your family.
I do not recommend going to a strip club. I've never been big on them nor have I seen the need, especially alone. That's just creepy.
Call her every night if you can and let her know how lost you are without her. She'll appreciate it when she returns.
