Such a confusing thread Op, maybe indicative of your head space?
You say you feel the sexting was wrong, yet justify/minimise it with a million excuses
You say you have no time and don't work, yet you work on OnlyFans and spend a fair chunk of time on social media
You say your dh side lines you and won't talk, yet you're working through all these issues with him and your relationship is fine?
My advice is to have a 6 month break from all social media/Onlyfans. Stop seeking the validation of men to fix your insecurities. No wonder you're depressed.
Spend some time on free online training courses- you can do them at your own pace and get a CV together. Make some plans to find a job when you're dc are at school which doesn't revolve around how you look, you have far more to offer.
Your self worth shouldn't be so tied up with sex, you think you're tough but I actually think you're damaged from this and very defensive and unwilling to change.
I hope you can, your dh sounds long suffering of everything you're offloading onto him
