I Am Lonely

I think there's something wrong with me. My boyfriend and i live in the same house. We talk casually and every time we were together i felt so lonely. I felt that he's not with me. Have you ever felt that way? When you were in the same room but it just felt so empty. I crave for his affection that he used to give me. The small soft kisses. The long hugs till i fall asleep. I missed those time that he is sweeter to me. I guess the spark is starting to fade. I could no longer see the excitement in his eyes every time he sees me. We've been together for 5 years now. I'm trying my best to make everything goes back. But it's not working and I'm getting tired of it.
