How good can love be?

I've never had such a relationship. How good can it be?

If this idea of love is between people, a partner, a family member…
My experience with my current partner (my 3rd time in a serious relationship) has been a good influence on me. I would like to say that relationships between two individuals can range on the extremes of how “good” they can be. A key factor to how you end up on the scale is how the other person’s mindset is. You both influence one another, sharing ideas, dreams, and even simple words or phrases.
My partner is someone I love and admire, who has seen the most vulnerable parts of my life as I have seen theirs. Positive love should be one that stems from pushing one another to be the best version of themselves.
