I've been on my own for a number of years now (barring the ageing cat, and my daughter who stays every weekend). I actually quite like it - no-one to moan at me for spending time on my hobbies, no-one wants to watch something on the other channel, no-one wants to go out when you fancy a quiet night in.
I'm quite used to it now and when I was in a post-divorce relationship a few years ago I actually found that I resented my every move being dictated for me. Guess living alone after 11 years of marriage makes you rather selfish of your own time!
Of course, there are times when it would be lovely to have someone there to snuggle up to and to have a blether to / laugh with. But I only need to wait 'til the weekend when my daughter's here. She loves cuddling up to her Dad and we love having a good laugh. Of course, she's 9 and no doubt giving your Dad a cuddle and spending time with him will be uncool in a few years!
