Been with my partner for 4 years.
Relationship isn't all that great he's always cheated etc.
Except this time he would have what I'd class as an affair.
He met someone through his work and was seeing her daily.
Telling her he loved her, they had made plans to have a baby together in time, sleep unprotected etc. and run away together with her kids.
I know I shouldn't blame her as she didn't know anything about me.
But I hate her. And I can't hate him 
It was going on for 6 months. I've had to listen to voice recordings of them having sex, seeing all their loving messagaes to one another and it just breaks me.
I made him change his job route so he doesn't see her anymore and made him change his number and email address as they'd even email each other. But I just feel like he will go back to her at some point as they was both heavily invested in to it.
He met her kids and family and the only reason he's gone no contact now and cut her off is because I found out.
She's now moved close to his new route and is bound to bump into him again at some point.
We are getting on ok and working through things we're engaged etc but I can't help but feel he will end up doing it again with her.
Just need to ask has anyone else experienced this? And they've gone back to the other woman. Even if it was just emotional or talking?
