finally back to watching!!

girlies, i took almost a year off but i am BACK! Forgot how much i was enjoying it before dawson's dad dies. I just need to know (spoilers welcome) why and how they ruin jen and dawson? They seem to be such a sweet couple in season 5 so far. I simply can't fathom them not working out, but maybe i'm just sentimental and maybe i just like dawson a lot more when he's with jen.
