i could write an essay on the topic XD, but i'll try sparing you the boring stuff..
i personally describe it like flying, you feel wheightless, kind of an overwhelming happiness! Also, love can come in many forms, like stated above, its not monotone. You can feel all kinds of true love, for your family, friends, platonic love and yes, the so called romantic love 🖤and all forms are equally amazing.
It is true that maintaing love is hard work and not a bed of roses as @Lïa said, but at the same time i also believe that it should be natural and most of the times it is, since you cant really force something that's between two different people (or you definitely shouldnt, as you also should not give up on it if your heart doesnt want to).
On one hand, and i think that this particularly apllies to you, it requires a level of vulnerability that can be hard for most of us, especially in the first stages of love or when we are not sure about what the other is thinking. On the other hand, love usually fails when there is unbalance in the relationship.. the feeling of love can be intoxicating and you should always try to maintain perspective of yourself and what you want or are aiming for in life, in a broader sense. There is not one love in life, but there should always be love in your heart.
You can only truly love others when you love yourself, and that is a tough lesson to learn.
As everything has a soundtrack in my head XD, i'll leave you with a song i heard a while ago, but came to me when i first read your post.
I'm done ranting XD. Hope it makes sense.
«Love is not something you try to do, it wants to be the thing compelling you..to be you.»
