While i ended up getting completely wrecked at a concert with a friend. We went to a club and then a party where I was way beyond my limit of what ive ever drank, and had taken an ecstacy pill. I honestly cannot remembee my night at all and I know cheaters use that as an excuse but I genuinely cannot remember anything. My friend told me in the morning that i had ended up kissing a guy at the party (no more than that) I wouldnt have even known this had she not told me and i couldnt remember the guy or what he looked like. Im completely heartbroken by my behaviour and apalled at myself, i hate cheating and i know i would never ever have done this if i wasnt completely out of control of my actions. Others have told me i could barely even speak that night. The guilt of it is eating away at me but i know it will be the end of our relationship if i tell my boyfriend as we've discussed what we do if the other cheated and he said he would end things immediately. It seems so unfair that this thing i cant even remember doing wikl cause me to lose all my friends and boyfriend over one stupid mistake. Do you think it is worth telling him or should i just learn never to get into that state again and not ruin our love. I know i will never ever cheat again. I cant stop crying about it and i just dont want to lose him because i love him so much. Please dont judge me.
