Is it normal that i don't care about break-ups?

I'll get straight to the point. I am a woman who, at the moment, is dating another woman. I am extremely pleased with the relationship. For the first time in a while, I'm content with my life. But, whenever I think of our relationship ending, I don't feel melancholy in the least. I feel as if I would wish her the best, move on with my life, etc. I love her, I don't doubt that, but I honestly hope she will one day find someone (if not me) that pleases her, and that she is comfortable with. It's always been this way for me. It's almost like I've been living in a constant state of nirvana, even though I've suffered every sort of abuse, ranging from sexual, to mental, to physical, to emotional, etc. I'm just... I don't know. Explain?
