Recently i've been speaking to someone and it has been about six weeks now. We started moving really fast very early on and claimed we were exclusive maybe a few weeks ago although we are not officially "girlfriend and boyfriend" yet which we have both stated and i genuinely am so happy with him. Unfortunate I made a huge mistake on a night out this week and i am devastated. I drunkenly left the club with another man and ended up having intercourse with him although have very faint memory of this and do not even remember leaving with him. I have been a wreck ever since and i know what I did was terrible and I just can't forgive myself although I don't want to tell him and hurt him and ruin what we have because if anything this has been a clear defining moment now that I realise how much I want him to be in my life. I have always been against cheating and never expected to do something like this and i am definitely not excusing my behaviour to alcohol but i genuinely would not have made this mistake if i wasn't drinking or if i was as drunk as I was. I really do hate myself for this and spend my time crying every night and ridden with anxiety 24/7 but i don't know how i'll feel with him although definitely do not want to lose him. I don't know what to do i've never felt more regret in my life.
