Don’t say never - it can find you at the most unexpected time and place. It can be different for everyone, but generally you feel and know that this other person would do almost anything to help you. Regardless of what you go through, you know that everything will be fine since you have each other. Being loved means you have an advocate and someone who validates you, despite all your flaws and shortcomings. It means you can be brutally honest with them, and vice versa, because you want the best for them.
Being in love means you can fight and argue, but find some sort of common ground and go from there - because they’re interested in your perspective and you in theirs, even if you disagree with it. At the end of the day, they’re your rock and your fire.
Another person shouldn’t give you purpose or meaning - everyone has to make that for themselves, and it will likely change through time. But it does mean you have someone to stand alongside you in that journey, excited and eager to share and experience the journey.
