Yes, there is life after divorce, but if you read enough, you'll see that it can be very lonely. Many of us were more lonely IN our marriage than we are now. Only you know if that would be the case for you but it doesn't sound like it.

YOu need to make 100% sure, he knows how serious you are about your needs. Tell him you are reading here, just considering what the other side might be like. Write him a letter...hit him over the head with a club. Whatever it takes. Men here would tell you they often need neon lights to get the message. If he is resistant to doing what you need, then you might have a problem. But if he even makes a little effort, praise him like crazy and hope for more :)

His Needs, Her Needs by Harvey _____________ (somebody help me here...) is a great book for where it sounds like your marriage is.
