I don't think the friend would tell. However it has been ruminating on my mind lately. I know that I don't want to know what my boyfriend was up to during that time. My conscious is just filled with this situation. I don't think my bf would take it too hard because he is understanding and open. But I don't want to feel bad after about telling him and worrying what he will be thinking of me. People have said "he could take that as fuel to go behind your back" which I highly disagree wih yet somehow it still worries me.
