Magic Forums

I've been researching Odinism, Asatru, and Heathenry on the web (not the best source to find a clear description) and I am not sure what the difference is between them? All I can find is that there IS a difference but nothing is telling me what it is?
I have been very interested in paganism for the past 4 years and I am now wanting to find a path and specific religion to follow and devote myself to, i just need to find the religion that falls in line with myself as well. I think I might be very interested in one of these 3 but I am having trouble understanding what they are about.
All I can really find out is that they are very focused on self responsibility (not blaming some evil spirit for their "sins"/ bad behavior and not blindly following a (awful) god, as well as being very family centered.
