But what do I do now? Should I be "grateful" he doesn't love her and wasn't going to leave? Whilst I can't imagine being able to forgive him, or being intimate with him, do I break apart our family for the sake of 2 weeks? I would find it hard with children on my own full time, and know that my 3 year old would miss daddy. It's worth mentioning that he does not usually work away, this was to be the last week. Any advice most welcome.
There's NOTHING about his lying and cheating that should make you feel grateful or relieved. So he basically used some woman for his own selfish needs while he was working out of town and now supposedly intends to throw her away like yesterday's garbage when he blows back out of town at the end of his work assignment? It's almost a given he lied to this girl and told her he was single. In fact, I'd bet the farm on that.
And since he had absolutely no qualms at all about conning some woman into spending time with him purely for his own amusement while he was away from home, his claim about not crossing the line 'physically' with her just sounds utterly ridiculous. That's kind of like a bank robber claiming he won't run a right light because it's against the law. Please.
The guy is a sneak and he's already proven to you he's more than capable of cheating, as he did years ago at the beginning of your relationship. He took advantage of his time away from home to get a few cheap thrills and when you caught him, he turned it on YOU and blamed you for it.
Considering his complete lack of integrity, that doesn't surprise me at all.
But do be warned - he feels completely justified for his sleazy behavior. Instead of feeling horrified for how he's hurt you, he's JUSTIFYING what he did. That means he has zero remorse.
He'll cheat again the second the opportunity falls in his lap. You can jump around like a trained seal for the next 50 years, doing his bidding, bending over backwards to please him, giving him everything he desires, and he'll STILL cheat on you the second the opportunity arises.
I guess you need to decide how much disrespect you're willing to take from him.
Good luck to you.
