Just want to add that it is laughable to compare drama between two teammates who are dating each other with drama from a teammate who is experience boyfriend trouble.
IMO, it's a big mistake to make broad generalizations about the emotions of personal relationships. FP26 had some good examples of how "boyfriend trouble" can be every bit as disturbing to a team as a relationship between teammates that goes bad.
When it's time to play ball, play ball. If something is getting in the way, it needs to be dealt with in a manner that is appropriate for that specific situation.
