My girlfriend of 7 months is going to break up with me and i am completly destroyed emotionally?

ive been with my girlfriend for 7 months i am 18 and she is 17 going on 18 and they were honestly the best 7 months of my life. I started liking her the beginning of my senior year of high school and after i tried me best talking to her and that whole process i finally got the courage to ask her out. At first she didn't like me at all but when i asked her out she only said yes to make me not feel bad. But i didn't know that and we still had fun. But three months later she started to change. She stopped caring for me and started to ignore me. The reason why she did this is because she felt bad for lying. She wasn't aloud to date at first and she was lying to her parents for about 3 months. But she asked for permission before our 3 month and her parents let her. I asked her back out again on our 3 month on February 10 and she told her parents. After that things were PERFECT. We went on dates and we spent valentines day together and it was just great. We are both very christian but we acted very bad. We kissed and made out Alto and that didn't really bug us. But on our 4 month i told her that i loved her, i waited that long to really make sure i did and when i said it to her it was true. She didn't feel the same way because a guy before me broke her heart and she loved him so she was hesitant to tell me. At first i thought it was fine because she said she will one day and a couple months later she told me over text. I felt SO complete and happy at that time and she would tell me she did but over text never in person. She said it was like the love of a friend she had for me and it wasn't really true and i started feeling concerned. But i always looked ahead and thought that she will tell me formals sometime. Then our senior prom and that night was perfect. we went together and we had a blast. But we sinned horribly bad, on the bus ride home we kissed and made out way to much and our hands went to places that aren't supposed to be. The next day we decided to stop kissing and i agreed because i would rather have her love me then to kiss. Then graduation came around and once again our hands went around bad places. We were still sexually pure but we still had lust. After graduation we decided to stop doing all that stuff and i said again i would rather have her love me then to do all that. We started talking about marriage and that REALLY got my hopes up. But around 6 months we started to lose that spark and we didn't do much of the boyfriend girlfriend stuff like kissing so she wasn't feeling it. I began to be more like a friend to her than a boyfriend and she wasn't feeling it. All i had to do was get her to fall in love with me but its harder than it sounds. Without the lust she didn't have a reason to like me and it started to go downhill. I told her that kissing would help us but she disagreed and we almost broke up. She doesn't 100% like me and she lost Alot of interest. Some days i feel happy again but then she changes and says that she wasn't into me. Then after 7 months she said she wasn't happy and she wasn't comfortable dating because she doesn't know what love is. I Absolutely love her and she is my perfect match, but im not her match. I tried to convince her to let me fix things but it was still the same. I Truly love her to death and i thought we were meant to be. But she couldn't take it anymore. She liked me but she wasn't ready for a relationship. I was completely devastated and i didn't want to lose her but she was tn happy and i didn't want to force her to be with me. She is going to college 2 hours away and i was planning on transferring there but i know she is going to find the perfect guy for her and she would completely forget about me. I get HURT when i think of that because i cant imagine her with someone else and i cant imagine my life without her. We are going to have lunch and we are gonna talk things through but i know that's when it is going to come to an end. I am going to be completely sad and im not going to move on. I have such Strong feelings for her but she doesn't for me. I need help i cant cope with being alone and im not exactly a ladies man so i don't have anyone else. Threes so much that reminds me of her and without her in my life i wont be the same. She is going to take my heart when she leaves. She wants to be friends because she doesn't want to completely lose me but i cant be friends, that's killing myself slowly. I love her to death and no one else can make me feel like she does, she was perfect for me. My friends can Only support me so far and i cant stand the fact of being without her. I know i should move on but i am attached to her completely. I contemplate suicide but im better than that. Its going to be hard to live through this and im losing alot when she leaves and shes taking alot with her. i just want some help to get through this.My heart aches and my mind is
