Second. Not always, but if a person quickly falls in love with you, reveals all his secrets to you and after a week of communication confidently talks about love and a joint future. Do not be surprised if a couple of months after a conflict you find that this person easily switches between people. Third. If this person supports radical, not very popular opinions. In my experience, one thing follows another, and you can easily find yourself with a person who is against vaccines, hates Jews and has a portrait of Trump in the toilet. I can't say anything about the green flags, because everything I marked for myself, openness, honesty, care and other things, turned out to be fake in the end. They are easy enough to fake at a short distance, and they are not worth mentioning. I wish you luck in finding not perfect, but good relationships, and i hope you are not thinking about your ex anymore. It's always very bad idea to search for someone just to cover old wounds.

All my three relationships started in three or less days after i met the person, so i guess i am not the best guy who can answer this question :D however, a couple of red flags that I highlighted for myself. First. If this person does something for you or in front of you, it almost one hundred percent of the time means that they will do the same easily for other people, even if it involves you. For example. If they laugh a lot about their exes' sexual or romantic preferences, like to gossip about their exes, etc., In a couple of years or even months, you may find yourself in their place. If they cheated on there current partner or left them just for you, they easily will do the same for another person with you.
