Immediately after the war they stated that it was good if they were together. Actually, they spent the first year alone. Only after she started working in the Ministry, they lived together in the house in Godric's Hollow. For the first few months it was really good - Ron was there and he was looking for a job while basking in the splendor of being a  survivor. She herself was fascinated by work in the Ministry and had a lot of new energy to try and create a relationship.
