1) being love
2) loving someone
The Difference:
First let’s define love:
It’s a tender affection for somebody, feeling, desire, kindness, a strong liking, an emotion, a longing, and desire.

Being “in love” is an altered state. Your focus is on your partner and you can’t bare being without that person. You are in a bubbly state of a desiring feeling to want them in your life. You look beyond the present and start looking towards the future.You become smitten by them even on their worst days. You stop looking at what they can offer you and look more towards what you can achieve together. There is a unity between you and your partner. You’re enamored, besotted, love-struck.
“in” Love.. Your IN it for the long run, your not just sitting there your interacting to keep it, You are trying, Your mind is IN it your soul is IN it your body is IN it. That is why it’s called “In love” you took the dive!
However to have Love for another person, in contrast is closer to appreciation and affection. However you don’t feel that needing when separated you care about them in which you don’t want anything bad to happen to them. You’re not in that bubbly state. For you to love someone you lack that intense intimate feeling, and you’re not too focus on that person.
To love is; to cherish, to be kind to, to want to spend time with, to respect, to enjoy, to trust, to want to know better.
To be in love; to be smitten, infatuated, enamored, hooked, taken with, besotted, head over heels.
