Different Man than The One I Married

So for as long as I can remember I have always wanted 4 children, when me and my husband got married I had 3 and he has 2 that are grown. We have a pretty big age difference between us...

We dated for a while and he has always been great with my kids, as we were dating we discussed future plans and he knew I had always wanted 4 kids and he agreed that he would like to have one with me as well...

Fast forward 5 years, his oldest son and his wife had his first grandchild, I love his kids and I love the grandbaby, but now he has decided he doesn't want to have a baby...

Well this has caused me a lot of confusion and stress, which I know sounds crazy and stupid but every time I see a baby I just want to cry..

I have tried to talk to him and he has used every excuse in the book as to why he has changed his mind. I have talked to my friends about it and of course some say just make it happen and others say just wait he will come around. I can't trick him into it that's just not who I am. If we ever have a child I want us both to be happy and want it...

I dont sleep much, I lay there and think about all this stupid stuff as to why he really doesn't want a baby with me...I'm up at 4am making lasagna because I was tired of laying there thinking about it...

I just dont know what to do to get over this or what to say for him to see it in my eyes, I really don't want this to affect our marriage but it already feels like he is distant from me...
