SGB - I've never lived with anyone (bar DD - 16 now), and you're the only person i have ever 'met' in a similar situation - and it's wonderful that its someone who comes across as so confident, perceptive and sorted as you do.
I've never made a conscious decision to stay single, but relationships never got to the living together stage.
I have only realised in the last few years how free I am to make my own choices, spend time on my own hobbies, interests etc, even compared to friends in good relationships with a lot more money than I have.
Every room in my house (bar DD's which is to her taste - dark purple...) is decorated exactly how I like it. I can change stuff whenever I like.
Half the kitchen table is taken up by a quilt I'm making for my niece (5) & I don't have anyone asking me to move it.
She's actually having a sleepover here & is in my bed ATM as she will sleep later there - again no one else to consider (& I've more chance of a lie-on)
(My dsis, her mum, poor woman, needs some support at present - shes having a delayed attack of depression and anxiety after ex BIL had an affair & she threw him out). Again, didn't have to ask permission/let anyone else know, what way I want to offer support - can do it how suits me/sis.
She's terrified of being on her own - when she's ready I'll send her a link to his thread to show her the benefits of being single.
Being single is FANTASTIC! The longer I live alone, the better a relationship would have to be for me ever to consider giving it up.
