Hi, deranged candy. I can see why you are upset. Some men have a hard time having sex with a woman later in pregnancy. It could be on some level that he's afraid he'll hurt the baby rather than rejecting you.
I hope he can come to the birth, but honestly some men have trouble with that, too. Please don't be too hard on him if he stays away. Only relatively recently are men staying in the labor room. Can you think of at least one friend or relative who can be with you during labor and birth?
Congrats! How exciting! Please keep us informed.
You sound like a reasonable, smart woman.
