When passion takes over you, Aries is when you really realize that you are starting to feel something more for that person. You look for the ways and the ways to be close to that person and what you really want is for them to be by your side as much as possible.
You know this is serious when you feel that you want to live life without fear with that person. When you want to live with them a thousand adventures, a thousand trips, a thousand experiences, and you are not afraid of anything by their side. You don't care about everything else; all you want is to spend your life with that person because you know that with them, you can be a better person, and you can be the best version of yourself.
When you fall in love, Aries, you are all passion and pure fire. You love without limits, and the only thing that matters to you is to keep moving forward in your relationship. You even know that you are in love because finally, you stop being so afraid of the damn commitment.
