If I owned my home and I put my spouse (were not married) on the deed as a tenant common will he have any right to part of my property. I paid for it

If you do nothing:  in the event of a divorce, your spouse has an equitable interest in the increase in value of your home during the marriate.  That is without placing his name on the deed.  You probably could not sell the house without a court order in the event of a divorce unitl that issue is resolved. If you put his name on the deed, he'll have an ownership interest in the house that won't automatically "go away' in the event you break up or divorce.  As a tenant in common, if one of you passes away, your ownership of the property will not pass automatically to your surviving spouse. It would pass in accordance with your will or the laws of intestate succession.  If either of you have children to a prior marriage, the survivor may have to buy them out.  It's usually not a result that married couples want.
