But guys .. the thing is , I ' m falling SO hard for Brian . SO hard , it 's insane . He 's like the sweetest thing ever and writes me songs and burns me cds and treats me amazing - ly ... and Jenn does n't know this , she probably just htinks we 're some random couple - ing . I do n't really know what I ' m asking here , i guess maybe advice or if anyone else went through this .

Question: What is the reason that Jenn does n't understand the nature of her friend 's relationship ?
The speaker is uncertain about the relationship and has therefore not shared about it with Jenn yet
