OP, you have spent the last twelve years together childless. I think we can infer from your husband's past conduct the likely path this relatinship will take if left to continue. Furthermore, in the unlikely event you do have a child together, he will almost certainly be a disinterested father.
Neither of you is wrong, but you do have different, and irreconcilable, life goals. In your shoes, I would be seriously considering ending the relationship as amicably as possible.
I am also going to go against the other posters in one respect. Yes, you are only 31, but should you leave your husband you will most likely want some time to yourself to do a bit of soul searching (I would!). It will then take you time to find and settle in with someone who you care about and with whom you share similar goals. All this could take four, five years if you are doing due diligence, by which time you will be 35~36. Still young enough to have children, no doubt, but a) it becomes more difficult to conceive, and b) the risk of congenital birth defects - though small - rises considerably. You'll want to do NIPT testing which does not come cheap. And if your pregnancy isn't textbook a lot of clinics will want to pass you off on someone else.
I don't mean to sound too negative - I am sure you will have a healthy child in the future - just be aware you may have to jump through a few hoops to get there.[/quote]
My goodness, this is scaremongering. I had my kids at 35, 37 and 39. Conceived naturally within 2-3 months of starting with all three. No problems, no extra care or complications, no special treatment from the midwives, textbook births (or at least the complications I had with one of them were nothing to do with my age but a completely unrelated fluke). Yes, pregnancy and childbirth shouldn't be taken for granted but let's not scare people or overstate the difficulties for the vast majority of people.
