your homes bedroom or lake(acess from forrest)
I go to the lake see her there and after that I don't know what to do
Either you talk to her about the fight, but im not shure if thats an option. If not invite her to live with you, and then talk to her at home, it should be highlited red.
I found her and couldn't speak to her, on the next trip to lake there will be button search for elf
