I think his attitude might be the cause of those divorces, rather than a product of it. Frankly, I would walk, no run, from that relationship.
The guy I'm dating can be defensive/angry re: money ... or women ... or relationships/marriage ... or people who "want something." It's as though he's afraid of being used. (For context, he's been divorced twice.) Help?
It's heart-breaking, and a personal tragedy...but some people have been hurt so terribly that they can only live in the past, and in their bitterness. I am so sorry, but the chances that such a person will change, and begin to respond to YOU personally, and your qualities, are small to none.
It's the heart afraid of breaking, that never learns to dance
It's the dream afraid of waking, that never takes the chance
It's the one who won't be taken, who can not seem to give
And the soul afraid of dying, that never learns to live.

If he's been divorced twice and had to give alimony and child support. I feel pretty bad for him and I think it's sort of reasonable that he's paranoid. But if he's not treating you right ( ie Emotional/Physical Abuse or Distrust) than you should probably leave him.
But hey, it's your life. Do what you want.
