I cant take it anymore please help!?

Wow where do I start! My girlfriend works me to hard! She makes me have to run way, way to fast! She runs like a Cheetah and The best I can do Is a weird kicking motion almost like the Charlie brown dance.And she's such a acrobatic and she makes me try to do the stuff! Like that thing agents do when they jump up on one wall and to another and go up at the same time. Like is there a way I can get more fit or do I need to like dump her or what? Help someone.
