The chances they will cheat again are very good unless they take responsibility for it as a mistake and sincerely work on themselves and both partners work on their part in the problems in their LTLR. By doing this kind of personal and relationship work it is more likely that the person will never cheat again because s/he is no longer willing or wanting to compromise his/her integrity and their relationship. And because as a result of doing this work their LTLR will be so strong and both partners so happy and feel so loved in the relationship that neither of them would consider straying nor be vulnerable to it happening.
