I think a lot of it is just personal preference, really. There have been a couple of comments like "I don't need a handyman" or "I don't need a man to help" or "different needs". Like I said, I don't need that, either; I just find it more convenient than not, and as I also like a few other things about having a bf, it's quite a nice all-in-one package :) The question "why do people feel the need to be in a relationship" is also a bit off. It's not feeling a need, usually, is it? Isn't it usually wanting to be in a relationship, because of the nice aspects?
I also put my bed together; kind of symbolic, don't you think?! I definitely felt quite chuffed with myself, anyway.
I think that within my marriage, we fell into the usual stereotypical man/woman roles - and I accepted it, as those were the only roles he would willingly take on! So he did all the DIY, for example, and I kind of accepted that he knew more about it than me, through practice. I think it encouraged him to think of me as beneath him, as I was doing the more menial stuff. Moving into my new flat I found I could do DIY just as well, if not better than him, and within days rather than years. Sorting out all my finances, insurance etc. was also very satisfying (he used to do it as he is the native speaker here, but I can do it fine now). If I do ever move in with someone I'd avoid the stereotyped roles, which would mean finding someone who'd go along with it - even the current bf is more modern, and he's older than my ex. That experience of being semi-single has really made me rethink my attitude.
