Do you have any primary sources either way? Some ancestry trees are well done with good sources, some are careless click o philes (Meaning they just put in whatever they find on others work and don't really verify sources).
My suggestion would be to check any primary sources you have first. If you can verify marriage to your satisfaction, very good. If not you can list what you have now in the bio section and not add spouse in profile until you can document which one.,
