How to get over something that really bothers me?

How to get over something that really bothers me? hear is the problem, today, I was in church, I needed to talk to my Leader, and by the way, I’m mormon. I needed to talk to him about a relationship I’m dealing with. He wasn’t in church today, I couldn’t tell anyone else about this problem. I’m sort of involved with a man that’s originally from Nashville TN and lives in Kansas temporarly. I’m so turned on by him, and, afraid I might break certain rules of the Mormon faith. I keep calling him sweetie, nothing else everytime I leave him messages. I love his southern drawl everytime he talks to me, love his voice, and his sense of humor. I can’t seem to stop being flirtacious with this man since him and I been talking for quite some time. He is suposed to come out to see me in September and I’ve been real anxious. During church services, I kept thinking about him since he’s on my mind. I had to fight back tears since I needed to get this out! I can’t call my church leader for I know that him and his wife are away. I need some help as to how to stop being so flirtacious with this man I’m involved with before I do something that shouldn’t be right. The more him and I talk, the more I feel I’m doing something wrong spiritually. Please, if possible, give me some advice. I’d feel so much better.
