I(33F) snooped and saw that my husband(36M) has been getting into red pill stuff since we had our daughter and it’s really worrying me

I’m putting here because I really don’t know what to do, I’ve been married to my husband for 10 years, we have a 4 year old daughter and 8 year older son together. We’re both teachers but have been mostly working from home since fall due to everything, he’s also the assistant band director so he has to go in 5 days a week for 2 hours. We’ve had a very good relationship free from many troubles and we’ve been so happy together.

Recently I’ve noticed that he has been making comments that seem on some level sexist. Not overtly sexist but enough that after thinking on it you could tell it was rooted in sexism. He’d make comments about how some women we’re mutual friends with were married to “betas” as and at one point he said “beta bux(or bucks idk)” and I had no idea what he was talking about at the time and didn’t call him on it.

This week he made a comment that indirectly said that he was disappointed that I wasn’t a virgin when we got together. This made me feel like complete shit. I used to struggle with feeling bad that I had slept with people that didn’t deserve me before I met my husband and this just brought of those feelings back. At this point I realized something was up.

I know I shouldn’t have done this but I looked through his phone and laptop and I saw he had been visiting mgtow and red pill forums. He even had a Reddit account that was 4 months younger than our daughter. I really am at a loss. I don’t know what is pushing him in this direction, and I Don’t know what I could to to stop him. I’m especially worried that he might start saying things like this around our kids and turn our son into a misogynist and makes our daughter think this is how women are supposed to act.

I really need any form of help.
