Susie :hug99: I can truly empathise, as my hubby would love a child of his own, but I won't give him one because there are major risks involved. We did try for a while but I made the decision to stop trying as my son is 7 and I don't want to go back to the beginning all over again. We've had lots of talks about it all, as my main concern is that he'd end up resenting me for it, so I do understand where you're coming from.
I would suggest asking your hubbs if he would consider relationship counselling with you, as a starting point. It will give you a neutral and controlled ground to discuss your issues and fears without it being able to escalate into a row or someone flouncing off.
What about looking into something like fostering or adoption? Maybe you could say to hubbs that once the two of you have sorted your differences out you could look into alternatives?
