Oh dear the usual MN bingo of things to tell a childless person here.
I wanted a family. I had the husband for a while, but he was abusive so eventually I left. I then had many years alone and am now with someone. I'm 45. It was too late for me to have a baby 20 years ago. That includes any intervention.
I've lost count of the number of times I've heard the "you can just....." sentences.
I can honestly say that every woman, and man, facing infertility has considered every crackpot method of conception, every intervention and yes, adoption and fostering. I too made the decision that neither adoption or fostering are for me. I don't have to give a reason why not. They just aren't. End of.
The other set of "you can just...."conversations generally involve "travel lots" (I have a full time job with limited annual leave and was running a household on one salary so err. No, I can't); "concentrate on your career" (yeah, I love ,y career - but I wanted a baby too, you know? Like other people) and have loads of disposable income (ha ha ha). My favourite was always "move anywhere in the world" - technically true, but it would involve uprooting myself from a house I love in a city I love and leaving a company I enjoy working for, so why should I?
While I'm on this rant. Childless people don't have a Disney view of parenthood. We know it's fucking difficult mainly because the parents we know make a point of telling us at every available opportunity. You al, knew it was going to be fucking difficult and yet you still went and did it. Sometimes more than once. Why are we then patronised by tales of how awful it is?
OP. It's shit and you are completely entitled to come on here or anywhere else and rant and moan and do all the things everyone else does on this board. There will always be a small number of posters who give advice and take offence when it is not taken, others who are so convinced that their way of life is the only option and can't understand why people may think differently. They are knobs. Life is full of them. Mostly people just listen, sympathise and be there for you.
