Have you ever felt like you went back to your vomit?
Reminiscing about past loves that you try to forget. The love you once had for them now seems trivial. Was that even love?
Simple answer: no. If you're going back to your vomit, aka, sin, let that go. Let the whole thought go. Let romance go. All of that is from the media. The media wants to shove into our throats what love is. But:
love ! == romance;
Love isn't romance. Romance may make you "feel" love, but it is some fictitious representation of what love is. Let it go.
