Love triangle that I do not want to be in
I am currently involved in a love triangle that I want nothing to do with. I have been dating my boyfriend for almost three years now, and we are both attending the same college and living together. We have a mutual friend who I met last semester who I literally can not stop thinking/lusting about and I have no intentions of cheating on my boyfriend, but my friend who I like keeps putting the moves on me (even though I have already told him blatantly that I like him but will not act on my primal feelings for him)... sometimes he even hits on me in front of my boyfriend and it makes me feel as if I had cheated even though I have done nothing wrong just because I feel guilty for liking the guy so damn much. I can't stop thinking of him sexually, but I want to respect my boyfriend (who I am still fully in love with)... What can I do to stop thinking about this other guy in a sexual way? I see him almost every day (in and outside of class) and we all have mutual friends so it is damn near impossible to get away from him.
P.s.- I have already tried "spicing up" my relationship with my boyfriend by going on more dates, staying away from friends as often, spending more time together, etc. Now what?
