I think you’ve identified your feelings as you like him more as a friend than lover. You are stress eating because you are trying to suppress the fact that you really don’t want this person as a romantic partner, more as a friend. It’s ok to take as much time as you need to fully come to terms with your feelings.

There was once a funny episode of Sex and the City, where Miranda was stress eating and said she needed to go to the Betty Crocker Clinic (like Betty Ford Clinic).

This person is not the only person in the world. You are not stuck with them.
