Changes in behaviour made me suspicious including him turning into supposedly "worlds greatest employee" having been the entire time I knew him a clock watcher and "that's not my job" employee
Improving appearance in particular ways, showering "at the gym" when he'd previously had no problem coming home sweaty and stinking... usual cheater bollocks
Then I went on home computer and he'd left himself logged into email without realising and there were some dubious but explainable emails, then I started checking his phone (which he had become more attached to) and eventually found texts that were very much unambiguous
Was advised by relative to keep quiet and gather more evidence which I did, but I stopped having sex with him and claimed tiredness/thrush etc
He was sent on a work training course which was meant to be mon-fri but then he called on the Friday and Gave an excuse and said he was staying there the weekend.
Went and checked emails again (had worked out his password) and there was the booking for a double room for that weekend made months earlier.
Called the hotel and asked to be put through to his room and she answered.
She was a neighbour and supposedly also my friend so I recognised the voice immediately.
Shit hits fan, kicked him out...
Despite ALL that and her pregnancy (she would have conceived approx 2 months before hotel weekend) he STILL denied for YEARS even to the point of claiming the baby was premature despite a healthy full term weight and baby and mum discharged from hospital day of birth
Cheaters so often are insultingly stupid and treat us as if we're stupid!
We were 10 years married 13 years together
Police had a word with me as she had had to change her number and it was the main number for her business.
TOTALLY worth it!
I know I shouldn't.m but hell yes!
In my case doing nothing gave me some satisfaction...
He propositioned me day before their wedding by text. He could see I'd received/read it, but I didn't reply referring to it at all. Only to discuss dd attending wedding and arrangements.
I could have landed him right in it. Instead I did and said...nothing
I have it on very good authority (not dd) that he spent their wedding day and honeymoon and some time beyond SHITTING himself in case I told her! 
We both dumped him the day we finally spoke, and slowly became very good mates! I was her bridesmaid 3 years later...
Love this too!
@Zoolally loving yours too
@MillicentMartha who says they're happy? My ex and wife 2 try and make out they're happy to me, they forget/have forgotten we have mutual contacts in common and I hear the truth from them!
Examples not limited to but include:
Her dad lamping him for knocking up his daughter while still married and living with said wife and dd
Her mother telling her directly she was ashamed of her
His parents refusing to meet her until several months after 1st baby born
Both sets of parents faces like thunder mostly at their wedding
Her sister catching him cheating again and the sisters falling out because wife 2 wouldn't believe her
But to me they make out like they're a solid, happy committed couple 
So don't believe the PR!
@BunnyBoilerRhian you WILL get through this I promise sorry for how shit it is right now though
@sunnyzwei I used to work in the wedding industry, this happens more than people realise I'm afraid. Then those of us dealing with the wedding can end up deaing with scorned exes (not just women, men as women of course cheat too!) one woman was apparently engaged to 4 separate men at the same time! I don't know how the hell she had the time and energy! All came out because one fiances parents against her wishes (for obvious reasons( posted an engagement notice in the paper complete with photo of the 'happy couple'! The fiancé we thought was THE fiancé, his aunt saw it and basically then al hell broke loose! She was actively planning and paying for another wedding to another of the fiancés and I honestly believed she'd have committed bigamy if she hadn't been caught
