I'm sorry, I completely disagree with you. I'll explain in more detail why.
1. I don't consider love to be any kind of state of the soul. And I don't quite understand what this "state of the soul" is. So I disagree with the definition of love.
2. Your first situation. These feelings, such as jealousy, anger, etc., do not prevent love; that's why they say, "Jealousy means love." As for infatuation, I don't even know; infatuation lasts for a short time, usually from a couple of months to half a year. It is a strong surge, passion, and a lot of emotions. You wrote about passion above; passion is part of infatuation.
3. The second situation, a mother who stopped loving her child, whom she raised and brought up, seems like a fantasy to me. Maternal love, in my opinion, is the strongest; I don't believe that any fear can overcome it. That's why it is allowed not to testify against one's family; otherwise, there would be a lot of false testimonies.
4. I agree with the first sentence of the last paragraph. I disagree with the rest.
P.S. Are you a romantic? You elevate this feeling so much.
You disagree, but love doesn't need to be elevated. It already is what people strive for. It's not about romanticism, but about the ability to understand what someone is trying to convey. Don't live in a pink bubble. Sometimes mothers hate their children, kill them, or sell them. Anything is possible in life.
Never mind what anyone says. Read the Gospel; you'll understand a lot.
Infatuation can last for any amount of time; it is the desire of one person and has no response.
We are all not perfect; the laws are created by us, imperfect people, for ourselves (what can be said about the fact that there are different laws in different countries).

Chat here, don't listen to anyone.
Actually, it's interesting to read how others, and mostly young people, perceive this incomprehensible and incredibly pleasant state of the soul.
You were a little late with this topic; if it were a little earlier, when I was overwhelmed by the first waves, I would have written so much to you... Now it's a bit awkward.
In general, I'll tell you, there have always been pragmatists who seriously explain love as sexual attraction or hormones... Poor, deprived people; what can you say?
