Desperate help for relationship

I stopped reading when i read that someone got bummed , sorry.

Welp could just not go to the party and say your ill

Well you could be overthinking the whole thing tbh. When has a one night stand ever approached someone and said hey remember that one time we ****ed

Right im in this **** dilemma right now, (i know my grammar is trash please don't comment it )

Anyway so i cheated on my girlfriend a week ago until now i felt no regret and no guilt. i feel like ****. my girlfriend doesn't know. we've been together for a good 3 months and we love each-other. she's not exactly the super outgoing lets get shitfaced type of gall, slightly shy but kind. Anyway i was slightly under the influence and this extremely kinky girl starts touching me **** and yeh one thing lead to another. my mates one of them which i respect the 2 others who heard that i lost my virginity want in on the action and 1 of them just bum the **** out of this girl who he's never met and will just get all defensive if i say anything meanish. So while i was at my gf's house she went to chill in the cinema with those 3 (my mates) and we have like parties with like 50 people invited and the party is for my girlfriend and one of the mates of i dont respect and the one i respect it hosts it. so basically my girlfriend, host dude and bum guy should get to choose who comes but instead those 3 have a vote, host dude says no and the other 2 say yes. everyone else coming to the party don't know this gall and werent told. so basically she's been told she's coming. i can either tell my girlfriend and risk her breaking up with me and literally my respect and reputation from everyone being taken. Or i risk the one night stand coming along and accidentally or purposefully or someone else i have told spilling it and girlfriend loosing trust and breaking up. Please someone else help me.

So I think it is interesting that right at the beginning or your post you let it be known that you had no regret and didn't feel guilty......right until you realized you could get caught. You are not feeling bad about what you did you are concerned about your reputation. If you truly cared about your girlfriend this dilemma would be happening. You just don't want to have to face the repercussion of your action. Understandable but just acknowledge it's not the guilt that is driving you insane - it is saving how you look in your friend group's eyes. Most likely she won't find out at the party but eventually it is most likely she will find out. So how would you prefer that info get to her - through you or word on the street?
Hope this is a life lesson moving forward - the risk isn't work the quick reward.

1. No you don't love your girlfriend. If you loved her you would respect her and feel some compassion for her (but by your own admission you feel no guilt and no regret).

2. It doesn't matter what the other girl was like, you did what you did because you have no moral conscience. If your girl cheated on you but she said "Well the guy was super hot & kinky and started kissing my neck (and one thing led to another)!" would that somehow lesson her accountability? Hell no.

3. Well personally I hope all this comes out because your girlfriend really shouldn't trust you. You're a dirty little cheater with no remorse nor moral conscience! She really deserves someone so much better than you.

Really, you are a little piece of work. You are so preoccupied with saving your own sorry ass, have you considered how your actions have jeopardized this girls wellbeing (potentially passing on STD's like herpes to her, potentially humiliating her at this party, messing with her trust, disrespecting her by cheating on her etc)?

My advice: Confess up to her now, because I guarantee you that this is NOT going to stay quiet forever (the girl you had sex with knows, your mates know, her friends will no doubt know etc- it's already out). And how would you rather this come out;

a. In a nice quiet private room between you and your girlfriend.
b. It coming out during a very public party
c. Or the whole thing getting back to your girlfriend via 3rd, 4th or 5th hand etc gossip?

Do the right thing and be honest with her and let her go. You don't love this nice girl (and she deserves better than this). If you really wanted to be with her, you wouldn't have cheated on her.
