Babbies

So there is a 90% chance that my husband is infertile and every time we talk about what we would do if he is and I bring up the option of getting a sperm donor he shoots the idea down almost immediately. And goes straight to the adoption talk which I'm not against but being pregnant and carrying my child is something that I've always wanted but his reaction to me wanting that is making me not want children at all and it's not helping with my anxiety that he'll leave me because of it.

Any advice on what I should do is welcome but I mainly needed to vent.
