There’s a lot going on, emotionally, for college seniors. You may be graduating in May and going off to grad school, or jobs in different parts of the country, or back home to live with parents while you look for a job. That’s going to determine whether your relationship is long distance or in town, and once that gets determined, I think you have to wait and see if he’s interested in dating you or not. Or, you can decide to stay together and make your next grad school or job moves together.
Hope that helps! Let me know if you have any other questions.
