From my experience, the officials will be very curious about your relationship and will want to know if you intend to get married while in the US. The answer needs to be "no" and you will want to have the return ticket handy to help prove her intent to leave the US.
A return ticket is rarely seen in these days of E Tickets and are often less expensive than a 1 way fare so treated as largely irrelevant by Immigration. Better to have evidence of strong ties to home country such as a letter from employer stating date due back at work etc, mortgage or lease agreements etc etc. Intent is all in the mind of the interviewing officer. A visa does not however guarantee a right to enter the US as many have found out to their cost.
