When you love someone it could have been a feeling you developed or rather simply feelings of comfort which make you in turn love the person or than again simply loving the person because plain and simple you love them. Although, being in love is something completely different. When you’re in love, you have no emotional control. When you’re in love with someone all you ever want is to be with that person.
I guess the biggest difference would have to be that when you love someone you can still live without them but when you’re in love with someone living without doesn’t seem realistic. When you’re in love with someone it feels like an organ of yours that you need to survive whereas when you love someone, you can love them from a distance and don’t necessarily need to have them by your side. Being in love with someone and having them be in love with you back is a gift that shouldn’t be taken for granted. It’s truly one of the most beautiful feelings on this earth.
