[Thinking of everyone's feelings means everyone's feelings, including one's own, which are just as important. Or at least they are when Lance is advising other people about the subject, but do as he says and not as he does.]

That's probably something you should put more thought into before you make a final decision. Your emotions and well-being aren't more important than hers, but they're not less important either. Whatever decision you make should be the most beneficial to both of you, even if it's not perfect for either individually.
