I slept with his friend 😪

Molly

So i have been talking to this guy for a month and we finally planned out our first date. However before it happened I realized through his Instagram pictures that I had slept with his friend and we went out for a couple of weeks about 3 years ago. That relationship ended on awkward terms and I honestly didn’t want to see him ever again. So once i found this out I told “Will” about it and I also broke things off before we even started... I do feel bad because I like him but I just feel so awkward about the situation.. did I do the right thing?
