How old is your LO Flip flop, if you dont mind me asking. Sorry this has all got you feeling down but pleased for you that he has agreed to go to the pub less.
I completely agree that BOTH parties need to be on board for a new baby, but it would really help you if he opened up about his reasoning behind it and at least give you some sense of understanding too. Just not wanting to talk about it, isnt particularly helpful for either of you because you have no idea where you stand and he is brushing a subject under the carpet like its nothing. It's obvious its really important to you, and it would be nice if he would at least acknowledge the idea and together outline some future plans.
