It is possible to have more than one soulmate in your lifetime. If you feel that you and your cousin are meant to be together, this would not be out of the question. The laws regarding marriage of first cousins vary from state to state, as well as in different countries.
You might want to consider all aspects of this marriage, especially if you plan to have children. Children born to parents who are first cousins have been known to carry certain genetic weaknesses. I strongly encourage you to weigh all the pros and cons of this relationship and eventual marriage, then follow your heart.
Best wishes,
