Feeling broken. Throwaway acct 28/f

Soo I hv been married for three years now. It was AM but with an acquaintance and we had a good rapport n understanding all the while. We don’t hav a kid yet. Hes a nice guy. Nothing majorly lik red flags w him. I was scrolling through his insta when I realised he’s having another random insta page..I mean an all together different account ( with. A fake name) . I impulsively clicked on it and found he’s not following any friends or acquaintances.. it had a hero’s photo as dp and the following included only actresses/ heroines/ weird posting girls on insta/ models ( basically women showing adult content/ having a lot of male gaze) I was shocked to the core. The worst part is I opened the chats.. and OMG He’s been replying to random women’s stories lik HOT, Wat a bod, disgusting compliments.. obviously no reply from the other end.

I scrolled down a bit n noticed dat the chat threads were from the past 2 years but with some gaps in between. I also noticed that he’s been trying to text some random page on reddit( the adult ones) trying to get them to send pics/videos /even requested some page for paid content!

And one particular chat where in he requested for. MEET UP!!! At some hotel!! And the chat seemed like flirty .With some random woman.( like he’s willing to MEET n she had sent some payment link) but the chat was cut abruptly.

I don’t know wat to think of this Should I confront him? Should I take the matters to the family? Should I dump him. idk.

I’m still reeeling from the shock of it all.

Pls let me know what I can do!!!

Ps- I’m too scared to break this even to my best friend or sister. Everyone likes him. He’s like the perfect guy from the outside. I don’t know but it s really affecting me . To put it out simply, had it been a sister of yours going through this , what would you suggest?
