Bachelor Girl - This Must Be Love lyrics

What does it mean, what does it mean When you use my toothbrush What does it mean, what does it mean When I pay for lunch with you All day all night all week and still it donÍt seem like too much I wear your sweaters and you wear my shoes What does it mean, what does it mean When you do my laundry How come it's OK that you use your key to my front door You steal the blankets while we sleep I steal your last beer But I guess that we ain't keeping score This must be love 'Cause what else could make us act the way we do Just think it through This must be love And I don't think anything else could be to blame This must be love Like it or not 'Cause what does it mean, what does it mean You drink my dregs of coffee How come its okay when I buy you stuff with your credit card All day all week all month and still it don't seem like too much To spend a year with you won't be too hard This must be love 'Cause what else could make us act the way we do Just think it through This must be love 'Cause I don't think anything else could be to blame This must be love Like it or not What does it mean what does it mean Your wallet holds my photo How come each place I go seems so much better if your there We light candles stay up late Always hate to go I guess there's no chance we don't really care This must be love 'Cause what else could make us act the way we do Just think it through This must be love 'Cause I don't think anything else could be to blame This must be love 'Cause what else could make us act the way we do This must be love Like it or not
