Help getting my scorpio woman back
So i met this girl 3 and half years ago. we immediately fell in love literally before we met. the story how we met on myspace is actually pretty funny. anyways we talked for awhile and it was instant. but she was really shy and nervous to meet me but i felt such strong feelings i mustered up the courage to go to her house on valentines day and gave her roses that were died in her fav colors orange and green. mind you at this time she was 14 i was 15 now im 19 and shes almost 18. 10 days later i asked her officially to be my girl. she said yes of course. we've had many wonderful times together including going to hawaii last summer. but during the beginning of this year she all of a sudden wanted all these friends but they were bad like smoking pot drugs drinking bad. mind you before this time she always tried to control me like all i needed was her and stuff and eventually i came around to it. i felt so much love for her i gave up everything for her friends and all. and i honestly didnt care she was my friend and my mate it was amazing. well after that happened earlier this year she lied about going to the beach with them and stuff and she met a few guys or w.e. and we had a fight about it and she finally realized they didnt want her to be there friend but they wanted to do her. so things went back to normal immediately . well june first i went to the airforce and i came back 2 weeks ago. on my way home she tells me she lost all her feelings for me like she has none 0. i have no idea what happened because just days before she was saying how she couldn't wait she missed me soo much.. im very confused and i need help i want my girl back. we were supposed to get engaged and melt our grandparents rings this december to make our rings. she thought of this btw not me. But please help. i want/need this girl. I really feel like shes my soulmate shes absolutely perfect i love her so much. when i first got back i couldn't eat for 6 days...i want to marry this girl even though the pain she just caused me. how can i win her over again?
