So I'm happily in a long term relationship with my girlfriend and we love each other. At the beginning, I had a crush on her friend I guess, it was just slight flirting, nothing much really. However, my GF is extremely jealous and I know that. So recently, being an idiot, I thought to myself, "what if I thought of her friend when I'm kissing (etc.) her, and she finds out? She would for sure get really really mad". Even though I know 100% that I got no feelings for her friend whatsoever, I have now "paired" the thought of her friend with kissing my girlfriend. So every time I kiss my GF now, I tell myself "do not think of her friend", but low and behold, I think of her friend. Its really really annoying and I'm afraid to tell me GF, I know she will go crazy, and this is driving me crazy. HELP.
