True Love/Deeply in Love Question.

Ok, ladies, I have a question for you. I have been in one relationship in my 10 years of adulthood that hurt when it ended. I felt like part of me was dying. 
But, that particular relationship was horribly abusive, both physically and emotionally. And I am having issues dealing with that compared to other breakups. I love my SO. But, if we split tomorrow, I don't think I would hurt. I would be sad, but I wouldn't hurt like I did previously. 
Do all breakups when you are truely in love with someone feel like you're being torn in two? I just, I'm worried I have a warped view of love or have put up too many barriers since my traumatic break up and I am wasting my partner's time. If I can walk away and only hurt a little, how can that be love?
