There can be love without feelings and emotional attachment. I've always thought that love is pure and in its pure state, it doesn't have any attachments to it. It is the pure feeling of likeness, care and compassion towards others. More often, we tend to attach some different feelings and still call it love. This is why these days you hear things like, wicked love, brutal love, jealous love etc.
Having said that, the kind of feelings matter too because likeness care and compassion are feelings too. That's what defines love.You can love someone of the same and opposite sex, deeply care for them with no strings of romance attached. This is how the rest of the world should love each other.
