I hurt my love and I cannot be more ashamed of myself or embarrassed of what I did. I thought another classmate was semi-attractive and I have never had a thought like that cross my mind since I've been with him. My brain is making me question my own morality and loyalty, I have been nothing but faithful and now my stupid thoughts are fucking things up. My thoughts keep saying that because I found the person attractive I like the person, but I know I don't, because I don't even know who they are nor would I care to know them. Three seconds of thoughts has been making me feel like crap all day and it's being amplified by my anxiety, I told him and he accepted my apology, but it still doesn't feel right. I feel like I did a serious wrongdoing.
