I think you need to honestly decide where you want to be and who you want to be with because you fiance or ex-fiance for that matter does not sound like the perfect match for you. True enough you both have a daughter that just came into the world, and I know everyone says parents should stay together for the kids but this is not always the best choice if the parents are not truly happy with each other, it'll end badly and it always does in these situations... Pregnant women have a lot going on in their bodies which is why it is not completely fair for others to judge or take advantage of them during this period (which I am not saying you did at all), but this could account for why she's been weird or crazy lately. If you know in your heart that you're meant to be with her then give her the space she wants right now, that's all you can do and I mean you can't force her to move back in with you... sometimes space is just what a couple needs to repair and evaluate their bond... I say this because I've been here myself... If she doesn't come around then it wasn't meant to be and you'll find another all the more deserving of your affection... but i would do something about the baby because she can't just keep your child from you and your family
