zeezeek, I just want to say to you that you've had such a hard time, and I'm glad things are working out the way you want them to with so much to overcome.
There's a lot of hugely interesting posts here (so, thank you for such a great thread). I'm not going to join in the arguments, but just add what's been true for me.
I married quite young (24), but my DH got an inconvenient testicular cancer, and it ended up taking us 6 years to conceive, so my DD is v precious to me (not to imply anyone reading this who has DC aren't equally precious to them!). 3 of my BFs were childless, two still are (and are also single) and the third now has a 5 year old (my DD is now 13 1/2). There is a mis-match, I think.
When I have (for example) younger cousins who are thinking about whether to TTC or not, I always say to them, it's like a doorway you have to go through. On the one side of the door - the one you know - there's lots of fun stuff..... You sleep in til 10 or 11 at weekends, wake up, have tea/coffee, papers and sex (I miss that a LOT!). You go on holidays when you want to. I took a reasonable amount of drugs. You can be spontaneous.... All sorts of things.
You can do them to an extent when you have children, but not in the same spontaneous way.
But when you 'walk through that doorway' (have a child) it's like that scene in Wizard of Ox when she wakes up and it's all technicolor... But it's hard to explain to someone without a child how when they look at you and smile and the smile means "you are the centre of my world" what that feels like! Or how they flex their feet while they're feeding. Or how they wave their arms because they 're so happy to see you. Or how she blew a raspberry and we laughed so she blew more because SHE WAS ENTERTAINING US!!!! Or how cute they look in their first dressing gown. Or how my heart sings when she sends me a text that says "thinks mum, lv U x"
My BFs are still my BFs, but I can't talk about being a parent in the same way as new friends, who are parents I can. Becauuse it's too boring for them, and out of their experience. One of my BFs used to describe me as a "smug married" (before I had children).
My single friends have WAY more money than we do, and nice cars, and amazing holidays and the lifestyles they want and that suit them. I think there's a part of both of them that would give it all up to be in relationships with children. There's a part of them that loves every minute of their lives and would hate mine.
The BF who now has a child used to bitch about her circle of friends being inconsistent with their children, and I used to try to explain that 'yes, no does mean no, but if you get a "please" or something else you're working on, you might change your no to a yes". She now has a child and the bitching she does about the parents around her is somewhat different.
I do think there's a massive difference between having children and not having children (and no disrespect to those who have miscarried - I feel for you very much).
And I do feel - and I felt this before I got pregnant - that biologically, we are alive as women to carry children. I'm so, so glad I experienced pregnancy (the ever-amazing Worra posted recently that she told family she was pregnant before "the piss had dried on the stick". I got that!) and birth. I've done childbirth. It was amazing. I don't say that to many people because my firends who've not been there don't need to hear it and the ones who have already know.
But - fucking hell - I squeezed something amazing out of my vagina!!!! And it hurt (a lot). And I love what I squeezed out more than I can ever say. She snuggled me on the sofa tonight. And she looks like I used to look. And she's better than I ever was or could hope to be.
And I can only say that on an anonymous internet site.
