Should we send this guy an invite?

I will be posting the update here instead since I am still receiving PMs to update what happened. I am not allowed to post in relationships (mods told me I am not allowed to post an update thread there) so I got the advice from someone to post the update here instead. This is the post I posted about 2 hours ago on relationship. Will try my best to update it as time goes.

Here is my previous post for the people who did not read:

I will try to be as detailed as possible. I have had quite a few PM's regarding what happened and I got such a big amount of responses (both positive and negative) which i never imagined would have happened. I want to let you all know that the support I have received has been incredible (both in PM and on the post itself) which has helped me in taking my decision.

I am also sorry for not being able to respond to all the PM's, theres just too many to respond to but I would like to throw out much love for all of you who took the time.

I would also like to give a big thanks on my post to everyone who replied, I tried to respond but I noticed the thread was closed (i still dont know why mods close it) but I still want to give a big thanks to the people who took the time to give me advice. Much love to you all.

I basically left in the morning to take a smoke, my head was still messed up but reading all the comments on reddit helped me. I cant remember who, but there was one guy who said the positive thing about all of this is that I found out BEFORE i got married, with no children or attachments. I still dont think she cheated other than this night, nothing i found indicated anything else, I guess she wanted this to be her "last night" before settling down or soemthing, I honestly dont know and dont care.

When I was outside taking a smoke, about 15-20 minutes or something after I left reddit, she had woken up. She noticed the drinks out and asked me what I had been up to, basically came to give me a kiss and a hug. I followed through with it but honestly felt empty doing it, I didnt want to give her any hint of what I knew. She asked my why I had been drinking and why I didnt come to sleep last night and I told her I was just having some nightmares but everything was fine. I felt detached, like I was watching myself in third person through a tv or something.

She asked me if any stress was related to the marriage and the plans, i just told her something along the lines of "you know i love you, there is no stress i have for the marriage, how can you be stressed about the best thing in your life". She got herself done and left for work.

I basically started packing my most important things, my desktop, computer, most clothes and some other things. I planned on leaving things like furniture, TV and other things I really dont care about more than getting the fuck out. I just took the stuff most important to me so that I dont have to return here again. I dont care if she gets the rest. All in all my stuff added up to about 3 or 4 suitcases i would say (desktop not included in this).

I called and cancelled the venue we were supposed to be having the wedding at, apparently they take 15 % of the money for cancelling so early on because we were having such a big event, i told them its fine and I really dont care at this point.

I also saved screenshots of everything and have taken them with me.

Around 1 pm I called a taxi and went to stay at a hotel around 100 km far from my city. I didnt leave any note or pictures at home, I just left. I am planning on leaving to stay with a really really close friend who lives in a town about 300 km away, but i just needed the alone time in the hotel for some time to think everything through and process whats happened.

Around 3:30 pm my phone starts getting spammed with calls from my ex-fiance. around 3:50 I start getting calls and messages from her sister, her friends, her parents, my parents and a few of our mutual friends.

The only person I called back was my dad and mom. I have a huge trust for my parents, I basically spilled the beans and told them a nicer story about what happened, asked my dad to not say anything and also asked my mother not to say anything. I told them its ended, and that I wont be getting married no more. I also told them not to tell anything to anyone about what I told them, I trust them alot so I am sure they wont say anything. I didnt tell them exactly what happened, just that I found out she wasnt being loyal to me, i didnt think giving details would help in anyway.

Around 5 pm my dad calls mee back and is telling me my ex-fiance is completely hysterical and has basically broken down completely not understanding what is going on. I just told my dad not to intervene and that I need some alone time now.

I basically just shut my phone down and have been staying silent ever since, like a ghost. Been sleeping for a little, went to the pool here at the hotel and have just been taking it easy.

I dont know if I should respond to them now or wait some more? Her sister knew about what happened at the bachelorette party ( i have the texts to prove it, she even laughed about it and told her not to feel guilty, because its her bachelorette and that women should go all in on this night). I am seriously considering replying with to the sister, with just an image of the conversation where she is telling her this.

Once again, thank you to everyone who replied. I will update this post 1 or 2 more times and then perhaps go silent for a while, I know you are only aloud to do 1 update on relationships section. I hope this post wont get closed (still dont know why the last one did).

Time here is 10 pm soon.

TL;DR Found out my fiance cheated and I left without saying anything. Not 100% sure what to say or to at this point...

EDIT 1: since i still gett messages asking what happened i will leave this edit here. yes i did send the with proof to her sister (the part where the sister is talking about it) to her sister. i have since not received any call or message from the sister. my phone is still blowing up with calls and messages from the ex-fiance. havent read them though, yet. thinking of answering or something but i dont know what to say or do. might make another post later today so i can update you with what happened.

EDIT 2: Thanks once more for all support, sorry i havent updated, alot of things have happened and im too exhausted to write it all out today. I will head to sleep and try to update tomorrow morning with a new post. once again thanks for all support and all comments and feedback, i never believed i could have a community help me in such a big way. I might go for a vacation or something, dont know yet... i will just shortly explain that i really feel like neo in the matrix dodging bullets in slomo, however instead of dodging bullets i have dodged a slut wife, unwanted children with this wife, endless of fights and ton of depression. I honestly feel alot better knowing my life will get better. Shortly said about her, she has broken down and is begging me to take her back, so is her sister and friends. they also come up with the most retarded excuse of what actually happened (i dont believe them for 2 seconds) and much more... will let you all know tomorrow, going to crash now im mentally exhausted.
