Well, it sounds like the person is trying the a repliers or testing what they can come up with the understanding. Yet, If i did understand the situation, the answer is as follows: Go tell the girl that you love her & wish to marry her. Loving alone is not enough to prove your sincerity. No matter what you call it, the relation would always be called illicit & the offsprings, bastards. (Sorry, but this is a fact).

If she rejects, forget her. If she turns back to you (hopelessly) or you keep trying, there would be no respect for you.
