Is it infatuation or love? Please tell me the truth.?

My fiancee and I have been together for 3 years and 2 months. There are times when I'm scared that I'm infatuated, but I feel that deep in my heart there is only true love. He is the most sweetest, handsomest, most amazing guy there is. When I'm around him I feel so happy that I literally never stop smiling. When he hugs me I feel so safe like if something were out to get me he would stop it. When we kiss I get a tingly and warm feeling that I never want to stop. I've never been so jealous of my other boyfriends friends that are girls. I've never cried so much for a man. I've never ever cried for just getting angry at someone. Even though I know there are some guys who are good looking, I've never found them more gorgeous or ier than him. I've never cradled someone in my arms when they are sad other than babies. If I even picture myself or him breaking up, my body feels sick. Oh and I've never stood up for myself till he came around. So what do you think, am I really in love?
