Asked: My girlfriend thinks im getting boring?

Hello everyone, i am in a very big situation right now.
i am a sophomore in high school this year. i am supposed to be a junior but i got held back last year because i slacked off with my homework but have been doing a lote better then last year.

I dont like any of the girls at my school, to me they are just a bunch of sluts who have been only been going out with me for just a good time (As in a good night over…) and just had the reason to go to school the next day and brag about what she got to do with me last night and then like a week later they'd break up with me because they got what they wanted. i met my girlfriend on a online game and we were just friend for about 2 years during that time ive had a deep crush on through that relationship but we never really tried to connect till one night we started flirting and it got to the point were i poped the question if she wanted to be my girlfriend and she said yes. then i found out she lived all the way in canada and i told her i live in the united states. andwe've never had a day were we could spend a whole hour without skyping each other and could just talk for hours and hours about almost anything. she is the only girlfriend that ive had thats ever cared about my feelings and got the time to ever know me and love me for just who i am. And shes had almost the same kind of relationships that ive had, except shes still a virgin. all the relationships shes been in the guys just went out with her so then about 2 weeks later they could shove her hand down her pants and shove there tongue down her throat, and each time she they did that she broke up with them because she realized they were such complete pigs.

she is the only girl i have ever loved this much and the only girl i could ever see my life with. And she honestly the last chapter in my life, the only real thing left and if i lost her the last thing on my mind would be the bullet going into it. and one night i realized she had not texted me in awhile so i asked her whats up. and what i got back was just "oh nothing just really confused" and i asked what was up and she just told me that its nothing and i shouldnt worry about it. but i asked her one last time what was up if it was about her friend because some of her friends give her **** about haveing a long distance relationship with a guy she hasnt met in person and cant touch physically. and the thing she texted me back was "honestly your starting to get boring. there no spark anymore, theres nothing interesting to talk about anymore." and when i read this it felt like i got hit bye a plane. and i did not know what to text back to her because i was so shocked… but we talked about it over skype and she basically told me that she really still loves me more then anything in the world but she say the distance between us is hard to work with, that there isnt a spark anymore. i asked her if she wanted to take a break but she insisted that she didnt want to do that to me because it would hurt the both of us… and its true i could not handle taking a break it would tear me apart. We've been talking but i just don't know what to do anymore or text to her anymore. i want whats best for her because i love her so much. She doesn't want to take a break, or break up with me and i dread the day she just stops texting me or completely cuts off all communication between us.i know she still loves me because she still says it to me but i don't know what to think anymore. we text alittle then she doesn't text me back for another 10 or 15 min and it makes me think im getting boring again and not interesting.

she is the only girl i have ever put me in this big of a stump, or loved this much, or i have ever seen in my future. So if anyone could give me a answer to what i can do to bring the spark back into our relationship it would make me feel like i am not dead inside anymore because i really want this relationship to last for a long time and she tells me that everyday but i just don't know what to think.
