Its means you love someone no wait its even more than love because every second of your life you want them by your side on the good days and the bad one and no matter how hard it gets you stick together for the rest of your life
You love the person and care deeply for them, but that spark is just not there anymore, you don't have sexual urges towards them any longer, You don't want to end the relationship because you love them so much but you know it is not the way things should be. You should be happy with every aspect or the relationship, and they ask you for a reason as to why you want to end things and all you can say is you will never be happy, you can't help how you feel, You love that person s much but you are no "in love" with them
Its when one partner is a little scared to admit all the way that they're in love. So they confess to their partner their love, but with a little uncertainty. This way they show that they're still to scared to let their guard ALL the way down.
