Hi, Lisa.
Yes, the fact that what would have been your child's due date is coming up is causing you some anxiety. What will even cause more anxiety is the date of the abortion itself. Make sure you have someone close on that day. This will go on for a long time unless you are able to deal with it and even then, there will always be pain and guilt.
You have to find a way to talk to your partner about it. The fact that's he's avoiding it already indicates that he is himself suffering from it and the two of you cannot raise another baby with this issue being undealt with. Your relationship should be built on communication and not hiding in each other's shell. Guys are, shall we say, pretenders aat strength especailly if they aren't. IF you really plan to keep a relatinship with him, you have to learn to deal with things like this. Seek out a counselor dealing with marital issues to help you.
One suggestion I have is for you to visit
www.rachelsvineyard.org. They may have some ways to help you to honor your child and to forgive yourself of your past abortion. There is so much that needs to be forgiven and you have to start and once you've begun your healing, it would be time to help your partner with his own healing. Don't buy the strong guy routine. It's all an act. If he can't face up to his guilt, he's really weak and you need to work together to make him a father worthy of your children.
Pray a lot, Lisa. Abortion is something that we regret and need to be forgiven.
Please take care.
