OP, I really really feel for you, your frustration, anger and sadness, but I think you are also being unfair to your husband as it sounds that it's not a case of misleading you but just that he has changed his mind and that he is allowed to feel and right not to ignore it when it comes to having children.
When I met my OP at 37, I was over the moon when he asked right away if I'd want more children. I had two already but desperately wanted another one. I felt like I'd won the lottery not only to have met my perfect man, but one who also wanted children. I fell pregnant only 5 months after we met and we were both over the moon, unfortunately, I miscarried not long afterwards. He was as devastated as I was but was positive that I would fall pregnant again, except that it didn't happen and when we ended up in front of the consultant, we were told that there were issues both on his side and ours and the chance of being pregnant naturally again were very low. I felt like I'd been shot in the chest. We discussed it and agreed to go with IVF, but OH wanted us to settle first and therefore to give it 6 months. I was desperate to go ahead right away so this came as a blow, but I agreed.
6 months passed and I excitedly started to get things into motion when he said he had something to tell me, and then came the blow: he'd thought much about it for the past 3 months and realised that he didn't feel as he used to and suddenly felt too old to have children (42). It came as the same blow as it did to you and I too first felt very angry, believing that he knew from the first time IVF was mentioned that he had no intention on doing it.
Time has passed (8 years) and I now know that he was genuine and that his desire for a child really died gradually until it got to the point that he really didn't want it. He felt horrible for me, felt he was letting me down, but as he tried to explain, he couldn't help how he felt and couldn't pretend when the outcome could have been having a child who he never bonded with and he was right.
My ex has never made much effort to bond with my DS and the reason why I so much wanted another child was to have one with my OH so I could share this with a man who wanted and loved my children as much as I did.
I understand how hurt you must feel as it feels like it's taken away your utter desire to me a mum and that is extremely painful. However, the situation is circumstantial more than him deceiving you. After all, what did he have to gain to marry you knowing you wanted to be a mum so much if at that time, he already knew he definitely didn't want more children.
Unfortunately, it is putting you in the dreadful situation of having to decide whether to let him go or let your desire to be a mum go. If indeed you would not have married him if he had a vasectomy for instance, then you have your answer, but you can't force him to be a father just to please you, this would just not be fair on the child and you would end up resenting him even more for not bonding with the child, helping you more etc...
