Hugs hun
we have battled with this delimena so much over the past 10 years as well. So many discussions have ended in tears and heartache as we were at different stages with our decisions whether to keep on going or not!
I wanted another child and DH was just so happy and grateful for what we had with the twins . I am so grateful as well, but just felt that our family wasnt complete.
That darn maternal instinct just wouldnt shut off for me! I understood the logic behind his decision- it made so much sense, but I still couldnt accept not to keep on trying!

It is soo normal to feel the way that you do! But if it the right decision for you, then hopefully a sense of contentment should follow! This darn fertility rollercoaster just doesnt stop!!! It is just awesome that you have both reached the same point in your decision what to do!!! Acceptance will come with time! Hugs hun!

FWIW- we did 7 more cycles and we finally got a BFP which I m/c after 12 weeks.
DH then decided that enough was enough. I told him that i respected his decision and whenever he was ready to go again- so was i! 1 year later he said he was ready to go a full stim again. I waited booked in the next day at the clinic and waited for AF to arrive- it never arrived and we got a BFP naturally after 10 years of trying!! I was allready 2 weeks pregnant and i didnt even know- we had conceived the week before DH had decided out of the blue to give it another try!!
Our little miracle is now nearly 7 months old!!!!

DH has clearly stated that he is definately not up for anymore now! I would love more kids, but now I am realising that it aint gonna happen and I am fine to a certain extent with that- that is unless another miracle is sent our way again . . . . . lol

I firmly believe in desinty and what is meant to happen- will!

hugs hun and good for you for making a decision !!! It is a toughie!!
