I must have never loved him

I know I am a terrible person for saying this but I'm thinking I shouldn't of married my husband. He is a great person but I always had nagging thoughts in the back of my mind that I'm not attracted to him physically. I overlooked his features because we were getting along so well. I feel like we argue more now than we get along, So know I'm not connecting with him emotionally or physically. Should I consider divorce?
