An employer has no obligation to hire anyone, regardless of any promises made prior to hiring -- unless
the prospective employee relies to his/her detriment on the promise and suffers economic injury as a result. For example, if your boyfriend gave up a different job opportunity after being promised a job from this latest prospective employer, then he could sue for the lost wages from the previous job.
But, if the employer is just taking its time, and even if it finally decides not to hire, there is no legal recourse.
Your boyfriend may want to keep looking for work, because a prospective employer that doesn't respond in a courtious manner suggests that it may be a lousy employer to actually work for. Sometimes the best thing that can happen is to not get the job.
Hope this helps.
