It's a common misconception that only those who are young and in love can know if they're falling in love. In fact, it's possible to know whether or not you're falling for someone at any stage of life, as long as you follow the right steps.
The first thing to do is pay attention to your feelings.
It's been said time and again that "love is all around us" but this couldn't be more true than when we fall for someone, we feel different from how we usually feel because our brain chemistry has changed. When we fall into a relationship with someone new, our brain releases dopamine which makes us feel happy and contented, even though logically speaking it might not make sense.
The other person also affects your oxytocin levels, which is the hormone most commonly associated with feelings of bonding with another person.
When you fall for someone, it's also common to feel insecure around them or about your relationship. You may think that it's not normal to constantly doubt yourself because of what they say/do/think but every love-struck individual suffers from this form of self-doubt at one point or another. If you're experiencing this kind of insecurity then chances are that you're falling in love.
Compare Your Past Relationship
Secondly, take a look back at past relationships and ask yourself whether what you're feeling right now is different from how you felt while dating other people in the past. Although we can't always be entirely sure if we're in love with someone, we can learn from lessons in the past and look at how different people make us feel before we commit to a more serious relationship with them.
If you're wondering if you're falling in love then it's important that you actually know what falling in love feels like. Many people think they're "in" when they're not--so maybe write down what you think your feelings should be toward this person before taking the next steps toward being able to tell whether or not it's true love.
It can also help to consider why you want to move forward into an actual relationship with them e.g., are there reasons for this other than just liking their appearance? If so, then chances are that it is love.
He/She Is The One
Thirdly, you should be able to tell yourself that the person you like is "the one" if they make all your worst fears and insecurities disappear in an instant. Although this might sound like a complete fantasy, falling in love does make us feel invincible for a while! If someone who has never made you happy before or given you a reason to smile suddenly makes you feel happy when they're around then chances are that it's love (and not infatuation).
Pay Attention To Changes
Lastly, pay attention to how much your relationship with them changes over time--most people fall in love only when their feelings deepen and grow richer after months together. This doesn't mean that it's not true-but rather than just thinking about whether or not you're falling in love consider whether or not you're in love.
If you're still unsure of whether it's love then don't worry--if your relationship with them has changed for the better over time and if they make you feel like the best version of yourself, even when they're not around, then chances are that it is!
If all you think about is him / her. The moment you wake up he / she is the first person who will remember and he / she will be the last person on your mind before going to sleep.
