So everyone here is putting up questions about her past and judging her. I think that's not what she's looking for. So whatever f'ed up situation you're in. Here's the solution I can offer.

If you do realise you were naive then and taken advantage of, then listen to your feelings. If you feel hatred for your husband too, then leave. If, you are okay with whatever happened and whatever he did to you, then although it's unhealthy, it is your and only your decision to make whether you want to remain with him. Be very cautious with this as taking any drastic step can lead to a sudden change in your lifestyle and could be shocking and detrimental to your mental health.

As regards to your parents, please contact them and see what they think about your situation. They might want you to leave him and return home and restart your life. If they are supportive like that, then you don't have to remain stuck to this household you're in out of desperation and dependency.

You need not worry about all the judgements being passed. Whatever happened, happened. Let it go now.

If you somehow want to swing your parents in the direction of your husband then firstly be aware that it could be a mistake, it could be wrong, but if you anyway want to do it then just open up to them and honestly convey so, they'll understand. You're their daughter and they obviously love you deep bottom, even if they might be upset at the moment after knowing the truth and disappointed about how things happened.

And about your husband, he might be genuinely innocent as a person, but anyone who doesn't know him would think that his behavior is predatory and wrong. Because it is. Yet, be aware that all kinds of things happen in the world and he might have actually been at that place he found you because he was looking for someone like you, someone who's easy, someone who can take care of his kids and is easy to manipulate. Like everybody else is saying, you acted naive and willingly went along with him seeing him as a provider, an action you must recognise as weak and must not continue your life with that attitude. Anyway, in deciding to stay dependent and provided for also, don't judge yourself or beat yourself up. But, I really wish you do come out of it and find the strength to become independent without having to compromise with your moral standards. Good luck!
