Ok so any help would be appreciated!?

Ok well like near the end of 2009 i poured my heart out to this girl... like full out and she turned me down.... she said she has only ever thought of me as a friend.. and that she loved her boyfriend alot... she has a boyfriend(remember thiss)...andi was really sad after she rejected me and everything but it made me a stronger person im alot more confident now cause i know the most they can say is no so im not as shy as i use 2 be.....and we are still best friends after that happened.. but today she asked me... if she went out with me would it stop me from going to the military? cause i am planning to go in april and she doesnt want me too.... i didnt answer the question tho my reason was... "why would it matter? its only a question so it wont happen meaning it would just be awkward after i answer so i dunno and im not answering that.."and then we were talking about like everything and i told her that i wanted kids.. im 18 and shes 17.... and she said ohh me to.. and i was like i want a little girl, she said not me i want a boy.. i was like yea i want both and she was like welllll ur outta luck cause i only want a boy... and i said well i want both meaning i would love them no matter which one i think id be a good dad... and she was like yea i would be a good mom too... then she said.. we should do it together since we would both be good at it... and i said "haha yea" thinking she was joking but then we ended up talking for like 20 mins about how we would raise the kid and everything... and i love this girl so much so i would love her to be the mother of my kids... she said she wanted to wait til she was 19 til she had kids.. but what should i do... she doesnt want me in the military... but i feel that its all i could do cause nothing else interests me... and if shes being serious about wanting 2 have kids with me... and not her bf she has.. which she also mentioned that she has 2 do something about him 2 get him outta the picture.... which is a good thing.. i dont like him... hes 24... shes 17... but i was really happy after we got off the phone thinking she likes me maybe more then a friend i mean why else would she be saying she wants 2 have kids with me? can some1 help and tell me if im right or not and explain what she was sayingg??? please and thanks
