Possibly ending a long relationship
I am 16 and have been dating my girlfriend for about 8 monthes. The last couple monthes, I have been feeling bored in our relationship. I don't find myself as attracted to her, I don't make as much effort to be with her as I did, and I find myself constantly thinking about ending the relationship. I feel guilty when I say I love her, because I'm not really sure if I do. I care about her and our relationship and I try to act like nothing is wrong but she can tell that I am a little distant. She has redoubled her efforts to try to preserve the relationship. I feel bad because I am not doing all of my part, but I also don't want to fake my feelings. She is extremely attached to me, so I feel like breaking up with her might crush her. Can someone give me some advice on what I should do?
