I've been in love with someone for nearly a year and a half. We are not involved physically, but are quite close friends and do spend a lot of time together. I find it hard when I don't see him and he has said a couple of times that he loves me. I didn't respond because I was scared and also someone once asked me if I was in love with him, loudly and in front of lots of people and I lied and said "no". Don't want to get flamed here. I'm just worried that if I tell him how I feel, it will ruin what we've got, but I also feel like if I don't, I'll burst.
