I'm so sorry that your experience of men has been so poor OP. Taking each separately.
It sounds like your ex is acting exactly from the male ex play playbook. The controlling is so common and actually there are some support groups that you could turn to for emotional support. Not sure if that's your thing or there's one near you but if it were me I'd do it, because I've seen the impact it can have on your life and self esteem. 💐
This new guy has proved to be a liability already. Firstly, he's cheated on you - had a one-night stand - which would be enough for most women to walk away. Secondly, its led to consequences - a child - which will be there regardless of what he now does. Thirdly he's spinning you some line about wanting children and needing to have a relationship, I'd be very suspicious. Is he from a culture where it's usual to have two families, because this all sounds deceitful to me, which would fit with the one night stand etc. There are so many red flags here.
It is possible that your terrible experience with your ex has left you feeling like you don't deserve better, or won't get better. Thats why you are even questioning your current guy. Hard though it is, it's better to be alone than settle for these duplicitous, manipulative creeps.
You're likely in shock and possibly denial, finding out all this about a relationship you thought was sound. Much as I hate to say it, it's not. 😔 At some point you will work through the confusion but for now, trust us, ditch #2 like a hot brick. He's an asshole.
It will be tough, but you will come through it. Dont let him 'gaslight' you into thinking you're to blame in any way.
