Break up while pregnant..

So boyfriend and and I broke up last week. He moved out.  Have been angry, sad, emotional neurotic.. Talk to my brother earlier and he suggested maybe I ran him off because I'm obsessed with being pregnant and that's all I talk, post, etc about.  Is there such a thing as being too involved and obsessed with my pregnancy? After all my body is possessed with a human life. It's hard not to think about it constantly...
