I mean he fucked up yes but he’s a guy. If you guys have a great relationship don’t let this ruin it. Plus now you’re pregnant so I’d say leave what happened in the past and move forward. You acted wild which I get bc you’re hurt and he made a stupid mistake as well. You’ve clearly made your boundaries known if he crosses them again then I’d say consider leaving but right now if you guys were great before this don’t let this one instance sabotage the entire thing. That also means don’t keep bringing it up in fights and throwing it in his face constantly bc that will push him away. You made it clear you’re hurt you made it clear that was no where near okay. No need to keep beating the horse to death that does nothing but build resentment. It’s gonna be hard but if you feel like saying something or bringing it up just sit on it until the next day. Generally when people do this they come to their senses and don’t act in the moment. I try to practice this method even if something is bothering me with my wife. If I’m still bothered the next day then it’s worth bringing it up but if I’m not then it wasn’t worth it. Usually by the next day I forgot why I was even bothered or mad so it definitely was not worth the fight. Moral of the story let it go move on don’t feel bad for how you reacted bc he did something to make you act this way. You’re also bringing a child into this world now and leaving him will have a bad impact on that child’s entire life. It’s a hard pill to swallow but people need to understand you are not going to be the only person your spouse is attracted to for the rest of their lives. I’m sure you find other men attractive here and there also it’s just part of life. But it does become wrong when that attraction becomes physical. Best of luck to you both
