Just be careful not to push the topic too hard. Men have been trained by the courts (Alimony, splitting assets upon divorce, etc...) to perceive such demands as an attempt to "steal" assets in a legal manner. Did his last wife "clean him out"?
I think you two are perfect for each other, only you two have a different perception of "marriage".
You perceive it as a status symbol (not a cheap shakeup) and life long commitment to another person. He has been married before and went through a divorce. Because of this his perception of marriage has changed to one of low regard and of little meaning. I suspect you may still have the "fairy tail" fantasy of what marriage is. I have known many young women who went through childhood fantasizing about getting married and having a big wedding in which they were the "beautiful princes" getting all of the attention for that day. If they ever got "too old" they began to panic and to think they were a failure because they had not fulfilled their fantasy. They also did not want to be seen as an "old maid" or "cheap shackup".
The bottom line is that you two are not seeing eye-to-eye on this matter and are both "dug in" on each side. This has caused communication to break down and subtle hostilities to sink in.
My advice: Seek couples counseling.
Don't think couples counseling is a sign of failure, it is a sign of potential growth.
I'm afraid you may be resistant to counseling because you may view it as a "failure" just as you view not being married as a "cheap shakeup".
Here is a very important question: Do you frequently fear that others are judging you because you are not meeting their own personal standards?
