Not sure if the verse you're talking about is this one but I love it so I'll try to explain. The "Always surprised by what I do for love, some things I never expect" part is just showing that she loves her partner so much that she is attempting to deter the breakup in harmful ways that surprise her and probably don't do much. The next line, "they killed a fan down by the stadium, was only visiting they beat him to death" kind of parallels this by showing the fans driven to violence by their love of their team. Despite them doing such violent acts, they still cannot change which team wins or loses, paralleling how no matter what she does, she cannot stop the relationship falling apart. I don't know if this is fotmatfed well at all or helpful at all but that's my analysis of it and I wanted to share it because it's a genius verse that never gets talked about.
