Tapeworm of concience

So something has been eating me alive from the inside. I feel like I'm deserting him and his Family. His family has done more for me than anyone in Utah since I've been here. I consider his Grandparents more my grandparents than my own! His parents have been there for me and worried about me as if they were my own parents. I consider his sister my sister. His brothers have developed a sibling-like comfort around me. His dog knows and loves me. I feel more at home at their house than any other place besides my own house in Chicago. I don't know what to do. I feel so torn. I love his family so much. I wish I knew how God felt about the situation. I hope that in time I will find out....
