I think wed just need the following

• rel.id (primary key)
• rel.user_id (foreign key to person.id)
• rel.user_id2 (foreign key to person.id)
• rel.type (type of relationship)
• rel.start (non null)
• rel.end

From there you don’t need a rel.status because you’re not updating this rel.id entry except for the rel.end. if they started dating again later it would be a whole new entry, and then you could query their entire dating history to see if they keep coming back to the same person, dating around, playing the field, etc. Separately there could be a friendship relationship that is tracked so you could if they ended being friends after a breakup.
