Argument
"No! I would never do that, I mean the guy never existed, he is not here, I made him up to make you and the others give up, because I couldn't choose between the three of you and when I did make up my mind, the thought of staying without you when I am back there, kept bugging me and stopping me from committing to anything, so I rejected you." Roselyn said, heating up the conversation even more and making Jonathan irritated with her response.
That's why she told him to give him up? She was scared of living without him, what kind of stupid thought is that? Of course there is that possibility, of course they might change and their love might disappear, but that doesn't mean they have to be scared of being together, it's better to get what you can than be scared of reaching for something because it's too far away.
