emotional cheating

I feel like this is cheating — having feelings for him, so I feel bad. I have thought about ending things with my boyfriend. Am I an emotional cheater?

I never thought that I would be the sort of girl who would take part in infidelity, but I have cheated six times. Before the first time, I told myself that if I got to the point where I wanted to step out on my partner, I would end the relationship before I crossed the line. I told myself that the emotional damage that I would inflict on my partner would far surpass any thrill. I told myself I would feel immeasurable guilt.
