Best friends dating - mostly girl answers plz?

hhahhaha. that's kind of the story of my life right there. i had a best friend and we had a thing but he hooked up with my best friend& i hooked up with his. i'd say the best thing to do is talk until you have common ground. assume nothing at this point because it will most likely lead to heartbreak. sometimes a relationship can ruin a friendship or a "thing" can ruin a friendship. before anything you gotta know where you stand with each other. if she really likes you then she'll tell you. but yeah just talk it over. and you might wanna be careful about kissing. it seems harmless but each touch brings you closer to heartbreak
