The singer and her boyfriend, owner of a night club in Siem Reap, have been together since 2012.
He has promised to give the singer whatever she wants and really wants her to be his fiancé.
But Eva doesn't seem to want to accept the offer because she's very busy with her career.
The source added that her boyfriend is also planning to make a business for her so that she could avoid entertainment all together.
Eva is regarded as a pure hearted singer because since her start in the business she has never been hit by a scandal.
Fans believe the singer is hesitant about another business because she is already happy with her career in which she could also earn a good living from.
Eva has not been contacted for further comment.
