Not always.

Maybe stopping could be seen as being brave and courageous. embracing what you do have and making the decision to be able to direct your financial and emotional resources elsewhere.
This is where i'm at - i didn't want to stop because it all became too much - i didn't want to stop because we ran out of money. i didn't want to feel like i'd failed. so, way back in the beginning of the AC journey, we pulled out a date (DH's 45th birthday) - and no matter the outcome, AC stopped then. it was something i needed to do - something that i could see as an end. i would have (and did) do just about anything in the time before then - we both worked ridiculous long hours (him in particular), excessive travel etc, so that we could afford it. i had multiple surgeries before even starting IVF to try and correct things. but it was always with an end in site - we were either pregnant by July 30, 2010 - or we packed in the towel, and shifted our focus to something totally different.

after having DD, i briefly entertained the idea of going through it all again - she is this magnificent little person, and to give her a sibling would feel like the right thing to do - but at the same time, I can't. I won't. i am tempted, but ultimately, i have decided i'm not going back, and i won't (unless i amazingly become so uber rich that work doesn't matter and i can do everything with no thought to the expenses or to losing work).

all of this has been discussed with DH (many times over!) and he understands. as much as he (we) would love a big family, it's just not something that we can do. it wasn't an easy call to make, and it's something, as i mentioned, i have waivered on (and i know DH does to - the man notices signs that might maybe just mean i'm fertile and tries to take advantage of natural chances....). but ultimately, we have to be strong, and invest what we have, fiscally, physically, and emotionally, in DD.
