i was abused when I was young. If you've never experienced it before, you won't understand it. It's best to take her to a professional.

Put yourself in her shoes then. What if she flirts with guys on the Internet? Does she have issues with security? Many woman lack the feeling of security, so when their husband show interest in other woman, it frightens them.

I have to take that in. I never thought about it that way.

Well, besides the fact that I'm against contraception, I guess I can't help but think that he doesn't want to get any OTHER woman pregnant. For whatever reason, it makes me think like he's in other relationships besides the one with your friend.
But who knows?... a guy's mind is a pretty scary thing to try to comprehend. Hopefully, it really was just for peace of mind, with nothing shady behind it.

I'm really sorry to hear this... I can't imagine what it must be like to lose your sight. But just keep close to your husband. I'm certain he'll continue to love you and be with you no matter what. And please trust in God too, He'll help you through this too, but only if you let Him.
