Ended Up Cheating On My Gf This Week…..

I have had the thought of cheating in my head for a bit. Nothings wrong with me and my gf but i just get sexually frustrated sometimes, the sex isn’t anything crazy and it leaves me wanting more. I often fantasize about past lovers that were better in bed than my current gf. So i was completely handed a g*ft this week. Came into my job for my shift and me and one of my hot ass coworkers that recently just started was clearly flirting with me. I knew what i was doing was wrong but it was exciting me. I flirted back with her here and there but we eventually decided to meet up later at my place while i was alone. Lets just say she ended up blowing my mind that night lol. Idk what to think, i’m conflicted over the whole cheating situation but i enjoyed myself so much with her and i genuinely feel a connection with this new girl.
