what does love mean to you all?

hey, so im (23f) currently going through a messy breakup after dating this person for 2 years. soo Im kinda lost with my definition of love now. I mean i know alot of people would say marriage and to spend the rest of their lives with that person, but marriage has never meant love to me because well, all ive seen growing up is unhappy marriages. hence i need your help... what does love mean to you? like what is the feeling you get when you know youre in love? what makes you realise it? lmk all the ways you can explain it
