So when you find out stuff by looking at his phone. ...it's your fault for looking at his phone, not his fault for doing it.
Cool. Gotcha. Highly logical and reasonable.
If he cheats with sex workers or whoever because his wife went away for a couple of days with his kids .... (Even though it sounds like he leaves you to do everything with the kids); it's because he, a married adult man with three kids, shouldn't be left alone for a couple of days and gets too lonely. Right. Absolutely reasonable.
Does he believe everyone in a couple who parts for a few days cheats and gets sex workers round?
Does he actually think that's normal?? If that's the case then he's clearly insane.
Does he he think he's special/has serious issues and therefore he can't be on his own for a few days without cheating or bringing sex workers around? What a very special snowflake. (I'd agree he has serious issues though).
If he's "lonely", he can see friends or relatives.
If he needs "affection" he can get it from you and the kids via video call.
Or by "affection" does he mean a fuck/a BJ?
He can get those from his partner - who he agreed to be in an exclusive, monogamous relationship with (though he's shat all over that and made a farce of it repeatedly) when he sees her next. If the meantime he can have a wank.
If you need company or affection, the very last ppl you should be getting it from, when you're not single and are married, is a sex worker.
It's all absolute bollocks anyway. You know that.
Why would he need to be left alone or lonely or needing affection to cheat??
He was cheating just as happily when you weren't away!!!? With non sex workers and sex workers.
He's like a child. A silly little child who makes up crazy excuses and rationalisations and thinks people might believe them.
I cheated cause you left me alone for a few days!!!
First off, I bet he's not have joined you if asked him to go.
Secondly, if your wife and kids can't go away for a few days without you using prostitutes for "affection" ...there is something very very badly wrong with you and you should not be in a relationship.
But it's all excuses anyway - it was a case of "cats away, mice will play" ... "I don't even have to pay out some money for a hotel room or bother my ass going to the location the prostitute is working out of; I can be lazy and have maximum convenience, and have the novelty of an "out call", and maybe get a special thrill out of fucking this prostitute in my family home; where my wife and kids live/function.
He's a thrill/high seeker, he seeks it constantly with drugs, he seeks it constantly with sex. Sex with his young employees, sex with prostitutes..... That's why he did what he did.
But he got caught and even Mammy found out, so he has to think up some excuses and blame. What/who can I blame, he thinks ...well my wife left me ... Left me!!!.Poor me. I'm just a vulnerable, little boy and really she should know better then to leave me alone, I was so vulnerable and lonely and needing "affection", what could I do with no woman in the next room to provide those for 48/72 hours .... Of course I called a prostitute. It's clear it's all really her fault.
And this is a winning approach because no matter what I do ...if I find a way of blaming her, putting responsibility on her ....she takes it. She swallows it, she keeps trying to change what I said was the problem. It's always worked before, so it might work again.
He's been scamming you for years op, have you finally decided to stop being scammed?
