So my bestfriend of two years and my fiancé of 4 were all having a good time drinking as always and I was completely drunk. I'm the kind of drunk to remember everything I do. But anyways, me being a dumbass asked for a three sum and well my boyfriend for 1 doesn't really like my bestfriend and my bestfriend had a crush on him way before I did. They were co workers.. Well anyways, she went down on my boyfriend and after that I completely flipped cause she was bragging to me about how great my boyfriend was. Mind you it technically wasn't a three some I did nothing..... What should I do? I'm broken.
