Yes, I've been there. And yes, we're still married. But there's nothing I can suggest you do. The ball is completely in your partner's court.
We'd been together since we were 17, never known anybody else, married 3 years, since we were 26. I was 3 months pregnant with our first at the time. We're now 5 years on, with two children.
I took the verbal abuse I rightly deserved from him. He called me every name under the sun. He wanted to know why. He thought we were happily married, expecting our first child. I tried to give him the reasons but to be honest they sounded pathetic. I was being bullied at work by one guy and sexually harrased by another whose wife was sending me abuse by email as she'd found his messages and been told it was my fault. My husband wanted nothing to do with my situation at work and a work colleague supported me through it instead. One thing led to another and I'm ashamed to say I fell into this guy's arms. We had an emotional affair for two months but then I slept with him twice.
My husband only took a day to process it but then he wanted to talk. I was all for ending it. I thought you can't fix these things, that I'd betrayed him beyond redemption. But my husband said he didn't want to lose me, he wanted to move on, forget it had happened, fix our marriage. I then agreed to do anything to make it work. I blocked the OM (it helped that he admitted he'd only slept with me as I was an emotional wreck and pregnant so he knew I was vulnerable and no commitment risk, so yeah, as much of a dick as me). For about a year afterwards it would come up in arguments, but since then we've never mentioned it. He's asked me never to talk about it again or mention it to anyone because he's ashamed. I have done everything he asked.
I'm not sure what to say. There's nothing you can do but wait and listen to what he had to say.
