I'm just not down anymore..

I'm OBSESSED with my man and I have been for almost 6 years now. I honestly couldn't imagine myself with anyone else and I'm so thankful for being with him. But for some reason, and don't get me wrong- I've never been more attracted to someone before, I'm just not interested in sex anymore. I had a abortion in the beginning of summer and it was one of the saddest things I have ever experienced and it will haunt me for the rest of my life. So maybe is that why? Help me out ladies, my man doesn't think I love him anymore..
