My long distace girlfriend mite be a guy....GOD HELP ME?

ok so this girl and i started talkin about two months ago, and over the time we have gotten rlly close. despite the fact that she lives in tennessee and i live in northern ohio. we have never seen eachother, but the more we talked the more emotionally attached i became. no i rlly want to see her. ive told her secrets, shes told me secrets...shes even told me she loves me. there is only one minor detail, i think some lil freak made her up, like he is actually her. now when we talk on the phone its definitly a girl i talk to, but everything she has told me about her past is basically the exact same thing he has posted on his facebook wall. he is obvioulsy gay, and she is the one who introduced me to him. she has told me things like she wants to cook with my grandma and meet my family. but now ive seen all this hard evidenct that says she mite be a dude, i truely love this girl imaginary or not. i actually cried histarically when i found all that she mite be this lil puke. they have the same cell phone number, and some how the same house number, she has told me before never to call her house cause her mom hates me, but i did and her mom seemed rlly nice....idk wtf is goin on...she tells me shes moving closer to where i live soon so i can see her...but i just dk wat to think i rlly need advice....she says girly things, and talks all girly, and all in all a girl, but this hard evidence is just difficult to ignore...i asked her if me and her are real...she said yes....and tells me to just trust her....i even found pics of her on the internet...so idk if its rlly her...i rlly hope she turns out to be a chick if she doesnt ill be crushed...shes basically my dream girl, unless she turns out to be a guy then i guess ill have to beat someones a**. she says that its just a coincidence that her and this kid are related...they're parents even have the same names....i just need some help...should i believe her or kick some lil dude in the nuts
