Is is normal to not want to be near your significant other while pregnant?

Since I was 4 weeks pregnant (I am only 8 now) for some reason I can't stand to be near my boyfriend or even be touched by him. All I want to do is be alone, this could very well be me trying to be independent because I have been all my life. I feel like such a bad person to feel this way and I am trying to change things. Just wondering if this is a normal feeling in pregnant women.
