Should I end our relationship?

I am 16, my boyfriend is 19. We have been dating for about three months. I am feeling really unsure about our relationship, I have since we started dating. He currently is at boot-camp, and I have no way to contact him until the middle of August. When I first met him, he made it clear that he wanted to date me. I was hesitant because I have never been in a relationship before. About a week after we met, I agreed to be his Girlfriend. I didn't want to agree to a relationship because I was already unsure of my feeling towards him. But we started seeing each other. He left for boot-camp in June, so I haven't had any way to contact him besides a letter once a week and the rare phone call. Today I received a letter and he told me that he loves me. The thing is that I know I don't feel the same way towards him. I feel like we have moved way too fast. I feel like when I'm with him, time drags on. I dread spending time with him. I honestly would rather stay locked up inside of my bedroom rather than spend time with him, which is quite sad. I know its not normal to feel like this towards him. I have been unsure about my feelings towards him since I started to date him I talked to my family members and they told me that I should tell him that I want to take a break. I feel like I am just leading him on because I cant return his feelings. I want to tell him, but I don't want to distract him from his training. I don't want to break his heart though. I feel like he is more of a friend rather than a person who I can see myself spending the rest of my life with. He is going to be getting a phone in when he gets out of boot-camp, but I don't want to be waiting and dragging him along. I just am the type of person who doesn't like to hurt other peoples feelings. So Im really scared that Im going to break his heart, but if I stay in this relationship, I feel like I am going to end up breaking my own heart. I really need advice cause I am torn apart right now and I have no idea what I am supposed to do.

Hey Sabrina Its funny how today I just felt the need to help someone, googled it, and found this post. Anyway here goes, I too have been in the situation, where someone said he loved me, his name is Akhil and I didn't share the same feelings and I too am the kind who would be so very upset if I hurt anyone. But I got my act together and just did it for me.. Akhil, he got a bit upset when I told him I don't feel the same. We stayed friends. I ended up being with another boy for 2 years and due to problems he had medically & family, it got too hard to carry on, so we had to split. And you know what the best part was? Me and Akhil remained friends through it all. He ended up maturing and being so supportive, after 4 years of being friends, we got really close and are now dating. Who would have thought right? Initially I could never see myself with him, AT ALL. And look how life turns out. And that's the lesson I learnt, be true to yourself and never rush things, if they are meant to happen they will. You just need to be strong through it all, if he cares enough for you he will understand and consider your feelings too. Its very normal for him to be upset initially and for you to be scared and sad, but he will get better and you too will feel good that you overcame what you thought you couldnt. I love this quote: "its always darkest before the dawn". One step at a time Sabrina. Believe me when I say, do what your heart tells you. If you say you dread spending time with him, then that is a clear sign somethings wrong. You can try to fight it, but its going to turn up sometime or the other, you will just end up making him get too attached to you and you deserve to be happy. You have a beautiful life and you need to live it to the fullest. These problems we have are very little in comparison to what people who are sick go through every day. So make most of what you have and cherish it.
