Husband Forwarded His Divorce Confirmation

I’m going thru a divorce in Oregon and my husband did it all online and then just forwarded me his confirmation email that had the document attached. It seems so casual and flippant isn’t he supposed to officially serve me somehow? I screenshot a section in the papers that talked about how to legally serve and he said “he hasn’t found any of that tbh” I’m assuming he is referring to the papers I have to sign? Idk it’s all so confusing and I’m not sure what I should do. To make things worse he leaves Wednesday morning to go out of the country to visit his affair partner and he has been pretty lazy with everything thus far. I don’t have a lot of time

To note we have no children and barely any assets aside from cheap cars, my husband has already given me most everything including cash in the bank, investments, etc.
