Me and my boyfriend have been together for 3 years, we met my senior year of high school and we've been together ever since. We are the best of friends and we can't get enough of each other. We of course argue sometimes but we always work through it and he's very understanding of my emotions. We finally moved in together about a year ago and things were going good until I lost my job. I found a new job after about a month but we still fell behind in bills, which put alot of stress on both of us. Lately we've been arguing a little more, we still always work it out. While working at my new job I met someone and he was just a friend, he would just say hey to me and maybe come and make small talk but nothing else. Well I ending up leaving my new job but on my last day my friend from work asked me for my number. He ended up texting me the next day telling me that he thinks I'm pretty and whatever, long story short we ended up having sex. I completely regret it and I wish I had the courage to tell him. It was a one time thing and never want to be with anyone else. I honestly just think I was just suprised to know that other men still find me attractive. I know I probably sound like a horrible person but I truly do love him, hes everything that I've ever wanted in a guy. I feel the need to tell him just because I would want him to tell me if he messed up. I'm scared that he will leave me if I tell him though, but the guilt is killing me. I'm not sure I can live with my secret but I'm not sure I could live with myself if I told him because I know it will break his heart. I've never cheated on anyone before this and it's breaking my heart every time I look at him.
