Am with misscathcart on this. I'm OK with the evenings on my own most of the time - pottering, doing my own thing, the quiet. But sometimes, out of nowhere, I get this terribly lonely feeling - that no-one-would-notice-if-I-disappeared feeling. And it sucks. Not all the time. But sometimes.
I, too, find weekends the worst. I have one single friend, who lives an hour away. All my other friends are just settling into married life/having kids, just as I've got off that wagon! And I feel I'm intruding if I see them at weekends - and it hurts to see others living the kind of life I really wanted. I feel sooo lucky to have my parents close by, and DS (3) and I basically move in there for weekends. It's just having other people milling about while you're doing your own stuff that feels comforting.
DS doesn't do weekends with Dad yet. He doesn't want to. But I know, in time, that he will, and I know I will find that tough, lonely, especially if I have no one other than Mum and Dad to descend on when the time comes. I hate it, when I didn't want this situation, that I have to relinquish my son for huge chunks of time to a life that has nothing to do with me, and which I don't particularly wish to know anything about.
Oh well. Am at my parents' place tonight, and they're fantastic, so I shall just feel grateful for that. Thinking of all of you.
