Reading through all of the love spells on the site before you attempt one is also recommended. There is also a love spell book available here . For a new love, or to have an old love return to you.
Love spells to get a person to commit are rare.
Many love spells will provide an obsessed partner, but that isn't exactly commitment. This commitment spell is extremely manipulative and most Witches would consider it black magick and against the Rede. It also contains some more difficult to obtain ingredients, but is easier than some. I would recommend practicing relationship and communication skills, and gaining the trust of your desired one by digging deep into thier emotions and listening carefully whenever they talk. Find out what makes them tick and see if you are compatable.
