Is a year too soon to tell a guy you've been dating " I Love You"?

I’ve been dating this guy for a year now and I have very strong feelings for him. I told him I love him but I never got a response. I don’t look for him to tell me he loves me In return so I often wonder how this makes him feel now that he knows. He’s different from any man that I’ve ever dated that’s why I feel such a strong connection to him. I’ve never had a compassionate caring man in my life and that’s another reason why I feel so deep for him. He texts me everyday with short sweet notes and tells me how beautiful I am. I see him when I can because I accept the fact that he already has a girlfriend. When I see them together I play it off, but am still confused because I don’t know how he feels about me. From the way he treats me I think he does care about me, but I need a second opinion. I cannot see me being with out him in my life. I know its probably seems like I am in the wrong but I’ve really never felt love in my life until now.
